Snubbies

The Four Formats

The shape of the integral hammer shroud on a Bodyguard creates a stop point at
the web of the hand, which keeps gun from rolling up in the grasp during recoil.

If you think the double action revolver is obsolete for self-defense purposes, you’ve spent too much time listening to the wrong sources. Trainers who do the courses to certify people for concealed carry permits tell me the short-barrel revolver is among the most popular guns with their students, and in some classes, the most popular. From NYPD to Chicago PD to LAPD, the “snub-nose .38” is still the most common backup gun among uniformed cops, and one of the most popular styles as a primary weapon for off-duty carry.

Over the years the Taurus Model 85 series of 2″, five-shot wheel guns has been consistently its best seller. Smith & Wesson is famous for its multiple styles of successful semiautomatics, and literally introduced the big Magnum type revolver, but still one of their best-selling lines is the J-frame: a small, five shot revolver generally produced with a barrel measuring 1 3/8″.

A little recognized advantage of the hammerless. Note how bore axis sits in relation
to hand and wrist with conventional J-frame, a Model 37 S&W Airweight .38, but
with web of hand all the way up on higher backstrap of “hammerless” S&W Centennial style

Model 340 M&P .357, bore axis is significantly lowered, giving shooter
much better control of muzzle rise in hard kicking rapid fire.

Variety

You can get small frame “snubbies” in a wide variety of calibers, though .38 Special is the traditional choice with .357 Magnum rising in popularity. You can also get them in a lot of brands. I knew a security professional in New York whose Charter Arms Undercover .38 saved his life when a psycho killer got his service weapon away from him. One friend of mine owes his life to a 2″ Colt Detective Special, with which he outdrew and instantly killed an armed robber who started the encounter by pointing a gun at his head. I debriefed two brothers in Virginia who killed a pair of vicious professional armed robbers who were holding up their jewelry store: the brothers returned a withering hail of fire with multiple Rossi fiveshot .38 snubs until one of them could unlimber a 12 gauge to finish off the last of these dangerous felons. A California Highway Patrolman of my acquaintance killed a man who had already wounded him and was reaching for the Patrolman’s dropped duty handgun when a Smith & Wesson 2″ Model 36 came into the CHP man’s hand, fatally ending the fight with five hits for five shots.

I guess what I’m saying is, the brand of snubby you carry may be less important than its configuration. There have been cases where the shape of the gun caused problems, such as snagging on a coat lining or a pocket lining when its legitimate user desperately needed to quickly clear it to save his life. You want to have a gun that is built and shaped for your particular needs.

The four formats. From top, spur hammer (Taurus 85 Ultra-Lite .38 Spl.), spurless exposed hammer (Ruger SP101 .357), shrouded hammer (.38 Spl. S&W Model 638), and “hammerless” (S&W Centennial Airweight Model 642 .38 Spl.).

The Four Formats

Unlike larger service, target, and hunting revolvers, double action small frame models can be had in four different configurations. Not every maker produces all four, but most have produced at least two and two do offer all four choices.

Those choices are: (1) Conventional, with spurred hammer, it can be thumbcocked for a light, short, single-action trigger pull. (2) Spurless hammer, in which the hammer is exposed but has no extension for the thumb to grasp for cocking. These may or may not be truly double action only in terms of internal mechanism, depending on the manufacturer and even the given production run. (3) Shrouded hammer, in which only the very tip of a hammer spur is exposed to the thumb for single action cocking, with the rest of that part shielded in a manner that renders it snag-free when the gun is drawn. (4) “Hammerless” designs, so called because even though there actually is a true hammer in the mechanism, it is completely enclosed inside the gun’s frame and not accessible to the hand
when shooting. The “hammerless” is a true “double action only” design.

Here, conventional hammer spur (on Ruger SP101 .327 Magnum) is easiest and
safest of all. Thumb on hammer spur allows trigger finger to be safely clear of guard.
Author has found no safe way to rotation check a “hammerless.” Note that
cylinder-turning hand is ALWAYS well behind the muzzle, muzzle ALWAYS in a safe direction.

No conventional spur hammer style revolver is more famous than S&W Chief’s
Special, this one being the new Classic version of the all steel Model 36.

Hammer Spur Style

This is your conventional double action revolver style as generally encountered with larger guns of the type. The hammer has an extruded strut called a “spur.” It is designed for the shooter’s thumb to “ear it back” for a careful, single-action precision shot. The cocked revolver will have a much shorter and lighter trigger pull than when fired double action, which requires a longer, heavier pull that rotates the cylinder and raises the hammer before dropping it to fire the next cartridge in line. In single action, the cylinder-turning and hammer-raising labor is done by the thumb, leaving much lighter work for the trigger finger.

With a light trigger pull, the good news is, “It’s easy to shoot,” and the bad news is … It’s easy to shoot.” Cocked revolvers led to so many accidental and/or negligent discharges over the years that a huge number of police departments had theirs altered to double action only. LAPD was the first of these, followed by New York City, Miami PD, and even Montreal. When this hit the radar screen of anti-cop lawyers, there arose a new and underhanded tactic: claiming that the shooter had cocked the gun and accidentally fired it even when they had in fact deliberately fired in double action. The reason was simple: in court, the most outrageous BS argument can be dignified as “plaintiff’s theory of the case” and given weight and credence, and it is established at law that while there can certainly be justifiable deliberate shootings in defense of self or others, there is no such defense as “justifiable accident.”

Some people who have not yet mastered double action shooting feel it’s imperative to have single-action cocking capability if they need a precisely accurate shot. As a rule, precisely accurate shots demand a different tool than a small-frame, short barrel revolver with short sight radius, but hey – I don’t make other folks’ decisions for them.

Cocked hammer, shown here on .357 Colt Magnum Carry, has become associated over
the years with unintended “hair trigger” discharges.

Retention Issues

The hammer spur has its uses apart from cocking the gun. Most thumb-snap holsters secure on the hammer spur, and if it is cut away,
the holster will no longer securely hold the gun. We old-time revolver shooters also like to perform “cylinder rotation checks” when we “load for serious purposes.” This means the hammer or trigger has to be drawn back just enough to lower the bolt stop, allowing the cylinder to turn freely and assure the user that there are no high primers that will lock up the gun he or she may need to fire tonight to save their life. Retracting the hammer slightly is the easiest and safest way to do it.

I own a number of revolvers that have been rendered double action only internally and which cannot be thumb-cocked, but still have the hammer spur so they’ll secure on holster safety straps and allow a perfectly safe cylinder rotation check.

Long before the cocked, lighttrigger revolver was recognized as having civil liability potential, street-wise cops and armed citizens had realized when drawn from concealment, the hammer spur could catch on fabric and stall their draw, perhaps fatally. One of the great police gunfighting authorities of the mid-Twentieth Century, Inspector Paul B. Weston of the NYPD, was perhaps the
first to point out a conventional revolver’s hammer spur was shaped remarkably like a fish-hook. Though it could snag on a coat lining, it was more likely to catch on a pocket lining. For about a century and a half, coat and pants pockets have been among the natural homes of compact defense revolvers.

Back in the Old West, the deadly gunfighter John Wesley Hardin was captured on a train by plainclothes cops. He tried to draw his Colt, but legend says the hammer spur caught on the watch chain on his vest and stalled his draw, allowing the officers to disarm him and capture him without losing any of their own. That time, it worked in favor of the good guys but, historically, good guys have realized the same mistakes could happen to them. This is why spur-hammer revolvers have fallen out of favor with those professionals on the side of law and order, at least for concealed carry needs and particularly for pocket carry.

Owning a conventional spurhammer revolver doesn’t mean you’re doomed to die from a stalled draw. When pulling one of these from a pocket, you simply put your thumb on the tip of the hammer spur. This doesn’t mean you’re going to cock the gun as soon as it clears, it means your thumb will act as a “human hammer shroud” to keep the spur from snagging. One of Inspector Weston’s contemporaries, the brilliant holster designer and fast draw champion Chic Gaylord, recognized and recommended this technique back in the 1950s.

Cylinder rotation check is trickier with exposed, spurless hammer, such as Cylinder & Slide
Custom Colt Detective Special shown here. Trigger finger must bring trigger back as shown,
dangerous on a loaded revolver, but at least thumb on flat of bobbed hammer can prevent
it from coming back enough to fire.

Spurless Hammer

With the snag-free draw in mind, some manufacturers began producing double action revolvers with spurless hammers a century or more ago. These days, several companies produce spurless wheelguns: Smith & Wesson (special production runs), Ruger (a regular option in their catalog for their compact SP101), and Taurus with their popular CH line. Charter Arms in its current Charco incarnation likewise offers this option. Even Colt offered such a variation in the last days of their late, great small frame revolver line. I may have missed one or more makers — it’s a popular feature. Countless professionals have “bobbed” conventional hammers by removing the spur.

As noted above, a holster designed with a safety strap that secures on the hammer of a conventional style revolver probably won’t hold it securely once the spur is no longer there. If you want a secure holster for such a snubby, one of the best is the SERPA from Blackhawk !’s CQC line, which secures on the trigger guard internally and is released by a discreet paddle button on the outside of the holster. This holster also works wonderfully with the shrouded hammer and internal hammer style revolvers we’ll discuss momentarily.

Hammer spur on this Colt has snagged on shirt button during draw from
belly-band. Spurless hammer, shrouded hammer, or “hammerless” designs
all eliminate this danger.

This discontinued Colt snubby has snagged on the draw, with hammer
spur caught in pocket lining. This danger was the original reason spurless
hammers came into fashion among professionals.

With thumb on hammer, this standard configuration Taurus 5-shot .44
Special snub can be safely pocketed or holstered. Drawing the same way,
the thumb acts as a “human hammer shroud.”

Too Fast?

In the old days, people who just practiced quick draw and shooting figured it would be a good idea to leave the single-action capability in place internally, and perhaps checker or groove the top edge of the “stump” of the hammer to allow cocking. This entailed pulling the trigger back “slightly” to raise the hammer enough for the thumb to get a good grasp.

Two real world elements were missing from this theory. One is that under stress, damn few people can pull a defense gun’s trigger “lightly.” This practice literally sets the stage for an unintended discharge. Second, the theory overlooked the fact that we often draw without having to fire, and uncocking the revolver without a hammer spur is literally a prescription for disaster. I strongly recommend spurless hammer revolvers be double action only (the way most manufacturers produce them today) to prevent these potential catastrophes.

One final advantage of this format is with neither hammer spur nor “frame hump,” one potential “bulge point” is somewhat reduced.
If you simply must have the “lowest profile possible” in your small-frame concealment revolver, the spurless hammer style may be what you want.

Cylinder rotation checks are tricky with spurless hammers. The thumb must press firmly down on the hammer as the trigger is brought back just enough to free up the cylinder. If doing this with a loaded revolver gives you the creeps, don’t feel bad; that makes two of us.

The defining “shrouded hammer” revolver is S&W’s Bodyguard, this one
being current production Model 638 Airweight .38 Special.

The shrouded hammer of the Bodyguard. This one is current production Model 638 Airweight.

Shrouded Hammer Style

In the mid-20th Century, Colt came up with a bolt-on device to shroud the hammer of their small frame pocket revolvers, such as the Detective Special and the Cobra. They called it, appropriately enough, a “hammer shroud.” It could be installed at the factory, or retrofitted by a gunsmith or even a mechanically skilled end user, by drilling and tapping three holes in the frame, two on either side of the frame below the rear sight, and one at the upper rear of the grip-frame’s backstrap. Leaving only the very tip of the hammer exposed, it allowed single action thumb-cocking, but effectively prevented hammer snag.

S&W saw its popularity, and countered in 1955 with the introduction of their Bodyguard series of small-frame .38s, with a built-in hammer shroud that was much sleeker than the Colt design, and used a differently shaped hammer presented a “cocking button” to the thumb. The downside was hammer shrouds, bolt-on or integral, literally collected “dust bunnies.” The modular Colt was easier to clean, and Bodyguard users who were wise learned to run a Q-Tip™ or a pipe cleaner in there regularly. The shroud of either brand could even pick up coins from the pocket the gun was carried in, though the hammer’s movement would usually just throw the coin
clear when the trigger was pulled.

While this design allows single action cocking, it brings with it all the legal baggage conventional double/single action design carries in that regard. Since only a tiny bit of hammer or “cocking button” was available to the thumb, it didn’t give much assurance of holding the hammer down when the revolver was holstered, if something got in the way of the trigger en route. One advantage over conventional styles was the shroud would catch the web of the hand if the grip turned upward in rapid fire, minimizing the gun shifting in the shooter’s grasp during rapid fire, and of course, there was no hammer spur to catch on the web of the hand and prevent the next shot if the gun did twist upward too much in the hand upon recoil. The Colt and its hammer shroud (which also fit many models of the Charter Arms revolver) are no longer available, but the S&W Bodyguard has remained in continuous production for more than half a century.

Note how much higher the hand can grasp a “hammerless” such as this Model 442 Centennial.

Hammerless Style

Circa 1887, Smith & Wesson introduced the New Departure Safety Hammerless, a top-break revolver with a long, heavy double action trigger pull; a grip safety which became known as the “lemonsqueezer,” and, most enduringly, an internal hammer completely shielded within and inaccessible to the user’s hand. The intent was to create a handgun a child couldn’t fire, and the double action only/ completely enclosed hammer design was to prevent the little ones from cocking the hammer and creating a trigger pull light enough for them to actuate. However, what really sold the gun was its totally snagfree profile.

By WWII, this old top-break relic was history. Not for long though, OSS trainer Rex Applegate got into a shooting in Mexico after the War that changed things. He was carrying a Safety Hammerless chambered for the feeble .38 S&W cartridge because the little snag-free gun was easy to draw quickly in a tropical climate, and when he was attacked by a local with a machete he emptied the gun into him before the attacker went down. He suggested to his friend Carl Hellstrom, then CEO of S&W, the hammerless design should be
adapted to the little J-frame Smith & Wesson had come out with in 1950 for the conventional spurhammer Chiefs Special revolver. Thus, in 1952, the centennial year of a company founded in 1852, was the Smith & Wesson Centennial born.

It was before its time. Why buy a snag-free little revolver capable of shooting only one way when for the same price you could get a
snag-free little S&W in the same caliber that shot both ways? That was the conventional wisdom that killed the Centennial in 1974,
while the Bodyguard still sold well enough to stay in the S&W catalog without interruption. Almost immediately, however, a cult
following developed around the Centennial, and gunwriter Wiley Clapp led the public charge to get the “hammerless” Centennial reintroduced in 1990. In its various shapes, weights, and calibers, it has been the single best-selling S&W handgun ever since.

Cylinder rotation check can be safely accomplished with finger out of trigger
guard on this shrouded hammer S&W Bodyguard. Thumb has held “cocking
button” back enough to drop the cylinder bolt.

Lemon Squeezer

The “lemon squeezer” grip safety was gone (though it would reappear on the “retro” Classic series Model 40-1 of 2007). The Centennial sells in today’s environment because (A) it’s as snag free as you get (B) it can’t be cocked, exposing you to either “hair trigger accidental discharges” or false accusations of same, and (C) because the rear of the grip-frame rises higher than any other small frame revolver, the barrel sits on a lower axis to the wrist and forearm, giving the shooter palpably more recoil control in rapid fire.

The downside is you have to pull the trigger of a loaded gun to do a cylinder rotation check on a “hammerless.” I for one don’t do it. I load the gun, check by fingertip feel on the back of the cartridges for high primers, and close the cylinder. I trust the manufacturing skill of Smith & Wesson (and of Taurus, which makes a similar model called the CIA, which stands for “Carry It = Anywhere”) more than I trust any human hand including my own under pressure.

Thumb on exposed portion of shrouded hammer (S&W 638) has brought
it back enough to drop the bolt and free cylinder for rotation.

Choices Aplenty

Each of us makes our choice according to both our needs and our abilities. In my case, for example, I need a reliable pocket-size revolver. I’ve paid through training, practice, and competition for the ability to shoot it as well double action as I can single action. Therefore, for my personal needs, double action only is my choice. It’s generally one or another S&W Centennial for the
pocket gun, and when working for the police department, the .357 Magnum spurless hammer Ruger SP101 I was issued for backup purposes.

Your needs may differ. In a world where the small-frame, short barrel, double action revolver has proven itself valid for so very many decades, only the individual user can determine exactly which of the four primary formats will fit his or her specific mix of purpose and capability. And don’t forget you have to practice, practice and practice some more.
