The Smith & Wesson J-Frame: A Short History by DAVE CAMPBELL

smith-wesson-j-frame-revolvers-f.jpg
Many years ago, I was honored to be a guest at the Smith & Wesson factory in Springfield, Mass. To say that I was struck emotionally would be a big understatement. I began collecting and shooting Smith & Wesson revolvers more than 50 years ago, and the opportunity to visit and see the inner workings of this iconic company was almost a religious experience.

Among the thoughts running through my mind that heady day was, “I wonder if the guys who developed the Hand Ejector series of revolvers back in 1894 had any idea of how well they would be received?”

The Hand Ejector revolver originally came in two frame sizes, .32 and .38. Inside the factory, they were known as the I- and K-Frames. It would be decades before the factory nomenclature of letter frame designations would be divulged to the public via gun writers.

A bit more than a half century later—1949 to be exact—Carl Hellstrom, the first head of the company not from the Wesson family, had the engineering department revamp the I-Frame in order to produce a smaller .38 Special revolver. The changes involved slightly increasing the size of the I-Frame and changing from a flat mainspring to a coil mainspring.

This new frame was designated the J-Frame, and in October 1950, the first J-Frame .38 Special left the factory. It was introduced to the International Association of Chiefs of Police (IACOP) at its conference held in Colorado Springs that year. A contest to name the new gun was conducted at that conference. Because it was designed as a plainclothes man’s weapon, the name “.38 Chiefs Special” was the favorite name and it stuck. Eventually the .38 was dropped, and everybody just called it a Chiefs Special.

Initially, the Chiefs Special came with a 2” barrel, but by the end of that first year, a clamoring among policemen pushed Smith & Wesson to begin offering the revolver with a 3” barrel. Sales were brisk, but the small, round-butt grip frame made the revolver difficult to control with duty ammo. Two years after its introduction, the factory began producing a square-butt version of the Chiefs Special for those whose hands were larger than average.

The first Chiefs Specials had fixed sights, but beginning in 1955, a target- or adjustable-sight variation was made in limited runs. It has been produced off and on over the years in round- and square-butt versions with blue or nickel finish. The year 1957 brought about the numbered model designation for Smith & Wesson products, and the Chiefs Special was given the Model 36 name.

Smith & Wesson has always been at the cusp of innovation, and in September 1952, it began making the Chiefs Special Airweight with a frame made from aluminum with blue (anodized) or nickel finish. It was later given the model number 37. This revolver was originally submitted to the Air Force as a pilot’s companion—weight being an almost overwhelming factor for anything that flies—but despite its 10 3/4 oz. weight, the M&P Airweight was give the nod by the Air Force because it’s easier to shoot. In March 1953 a square-butt version of the Model 37 was offered with either a 2” or 3” barrel.

Another interesting wrinkle in the J-Frame series is the Bodyguard Airweight, introduced in 1955 as an aluminum-framed pocket revolver and given the model number 38. The Bodyguard Airweight featured a rounded extension of the frame that shrouds the hammer to prevent it from hanging up when drawn from concealment.

There is a slot in the top of the shroud exposing the checkering of the hammer spur to allow it to be cocked and fired single action. Four years after its debut, the Massachusetts State Police requested a steel-framed Bodyguard, and, of course, Smith & Wesson obliged, calling it the Model 49.

The Smith & Wesson Bodyguard lives on today under the company’s M&P brand name.

Bodyguards are sometimes confused with the Centennial models—now referred to as the Models 40 and 42. The Centennial was introduced during the company’s centennial anniversary, 1952—hence the name—and differs from the Bodyguard in that the hammer is fully concealed and the grip frame has a built-in safety that must be compressed to allow the revolver to fire. Like the others, there was a Centennial Airweight Model 42 with an aluminum frame.

By 1964, Hellstrom had died, and William Gunn was running Smith & Wesson. He initiated the research in producing the Chiefs Special in an all-stainless-steel form. Production of what would become known as the Model 60 began in 1965, and by the fall of that year, the new stainless-steel revolver was debuted to the same IACOP as the original Chiefs Special.

Sales and demand quickly outstripped the company’s capability to produce the Model 60. Initially, the Model 60 was made with a bright polish of the stainless steel, but problems with the hammer and trigger, and an outcry from police officers who did not like the flashy polish on their revolvers led to the company going toward a brushed stainless-steel finish.

Barrel lengths on the Model 60 have ranged from 1 7/8” to 5”. In 1996, a .357 Magnum version of the Model 60 was offered featuring a slightly longer cylinder and more modern heat treating to contain the higher pressure of the magnum round. As with its pappy, the Model 60 has been made in both fixed and adjustable sights. Today it is made with a 3” heavy barrel with a full-length underlug.

The original I-Frame Hand Ejector Model—later called the Model 30—was chambered in .32 S&W Long cartridge, in barrel lengths ranging from 1.25” to 6”. In 1961 to simplify things, Smith & Wesson jettisoned the redundant I-Frame and all the .32 calibers were made on the J-Frame. Too, the .32-cal. revolvers are all six-shots.

As with the other J-Frames, round- and square-butts versions were made in blue or nickel finish, and special runs with an adjustable rear sight were made available. The Model 32, nicknamed the .38/.32 Terrier was a five-shot variant chambered in .38 S&W.

When the .32 H&R Magnum round—basically a longer version of the .32 S&W Long—was brought forth in 1984, Smith & Wesson initially ignored it, but in 1992 the company brought out an Airweight Model 032 in the souped up “Volkswagen” caliber. It was made for that year only, and currently no .32-caliber J-Frames are cataloged.

Smith & Wesson Model 60.

Another long-standing J-Frame has been the .22/.32 Kit Gun or Models 34 and 35. Debuting in 1953 these .22 LR revolvers with adjustable sights and either 2”, 4” or 6” barrels have enjoyed a fairly steady level of popularity among anglers and other backwoods’ loafers. They are still available as the Model 43C, an 8-round, .22 LR or the Model 351 C, a 7-rounder chambered in .22 WMR. Some feel that the .22 WMR is a decent self-defense gun, while others consider it only a trail, small-game or target gun.

Smith & Wesson has always prided itself in offering just about any reasonable variation throughout its product line, and what I have provided here is by no means exhaustive. One could write a book if every single variant were described. J-Frame Smiths remain as a very popular self-defense gun for those who need as much power as they can handle in the smallest package.

Some 30 years ago, I latched on to a Model 60. It and I have logged in thousands of miles together. When I left the factory tour in 2006, I came away with a Model 342 PD, an 11-oz., Scandium-frame .357 Magnum that I carry quite often today. I still can’t help but ponder whether those gentlemen who designed, developed and began manufacturing those Hand Ejector revolvers could imagine they would remain mainstays in the Smith & Wesson line 121 years later.

The Mondragon Model 1894

The rifle we are looking at is an early Mondragon bolt-action design, model of 1894. Prior to designing his self-loading 1908 rifle (which is notable as the first self-loader adopted by a national military), Manuel Mondragon created this bolt action design. He was working in Switzerland at the time, and the guns were actually built by SIG. Thanks to reader Bruce, we have photographs of the very first one of these rifles produced (it is engraved “1” in several places, and devoid of other markings).

This rifle has several very interesting features, and shows us some of the ideas being contemplated at that time. It is a straight-pull bolt action design, but the utility of rapid repeating fire was in its nascent stages. Instead of adding the extra complexity for a self-loading design, Mondragon put three selector settings on the 1894 rifle. Two are the typical “safe” and “fire”, and the third is for rapid fire. In this setting, the firing pin is released to fire a cartridge automatically when the bolt is fully closed. So the shooter needs only run the bolt back and forth to quickly empty the magazine, much like holding down the trigger on a Winchester 1897 shotgun and having it fire as you pump the action.

This early Mondragon rifle was made in two calibers. One was a fairly typical 6.5mm round, and the other was an unusual 5.2 x 68mm cartridge developed by Colonel Rubin (of Schmidt-Rubin rifle fame). It was an attempt to get a high velocity smallbore projectile with the less than fully developed smokeless powder that was then available. The cartridge used an internal piston, so that the case volume increased (and thus the pressure was moderated) as the bullet initially left the case. The rifle was have photos of here is in this 5.2mm caliber, which was ultimately dropped. Better powder made its special featured unnecessary, and it also occasionally had problems with the piston breaking up and lodging in the bore.

The 1894 Mondragon fed these cartridges from a 6-round en bloc clip much like that of the US M1 Garand (the 6.5mm version of the Mondragon held 8 rounds in the clips). A loaded clip would be loaded into the top of the action with the bolt open, and a catch in the back of the magazine well would hold it in place. A small lever in front of the trigger guard allowed a partially loaded clip to be removed. The magazine floorplate had a pair of flat springs fitted to it, which pushed upwards on a follower plate to feed the cartridges up to the bolt. The rear end of the follower had a swallowtail cut so that it would fit inside the walls of the en bloc clip.

The rifle used a very modern-looking bolt with two sets of six small locking lugs arranged radially, very reminiscent of a Johnson or AR bolt. One set up lugs locked into the front of the receiver, and the second set was located at the rear of the bolt, behind the magazine. Inside the bolt was a simple firing pin/striker with a captive spring and a foot to catch on the trigger mechanism.

A cam track in the side of the bolt (no visible in any of our photos, unfortunately) was engaged by a lug on the bolt handle, forcing the bolt to rotate and lock and the end of its forward travel. In addition to the cam and groove, the bolt handle rode on a rail on the right side of the receiver.

The idea of allowing the rifle to fire upon bolt locking without use of the trigger may have seemed to have potential back when this rifle was being made, but it creates a huge safety hazard. One would have to be extremely aware of the selector position if planning to carry the rifle with a round chambered. The model 1894 never saw significant production, possibly for this very reason.

However, Mondragon continued his work in arms development, and later created the Model 1908 self-loader. Interestingly, the 1908 still showed evidence of concern with bolt action and rapid fire use, as it incorporated a catch allowing the shooter to deactivate the gas system and operate the rifle as a straight-pull bolt action.
