The Smith & Wesson K-38 Combat Masterpiece, Revolver Model 15 is a six-shot double-actionrevolver, with adjustable open sights, built on the medium-size 'K' frame. It is chambered for the .38 Specialcartridge and is fitted with a 4-inch (100 mm) barrel, though additional barrel options have been offered at various times during its production. Originally known as the 'K-38 Combat Masterpiece', it was renamed the Model 15 in 1957 when all Smith & Wesson revolvers were given numerical model numbers. It is a shorter barrel version of the Smith & Wesson Model 14 Target Masterpiece and essentially an adjustable-sight version of the seminal Smith & Wesson Model 10 ('Military and Police') revolver with target shooting features. The main production run of the Model 15 was from 1949 through 1999. It was discontinued for approximately a decade until 2011, when a re-tooled version was re-released under S&W's Classics Revolvers line.

History[edit]

The Smith & Wesson K-38 Combat Masterpiece Revolver Model 15^[1] is a derivative of the classic 1899 K-frame (medium frame) Military and Police .38 S&W Special (aka .38 Special) six-shot double-action revolver. The M&P underwent steady evolution throughout the 20th century and S&W spun off several variations as separate models in the post World War II years. One of these was the K-38 Target Masterpiece, which began production in 1947. The Target Masterpiece included a number of new and/or special features, including a six-inch barrel with a narrow rib to provide a level sight plane, a Patridge front sight, a micrometer click rear sight, S&W's .375” short-throw hammer, a trigger adjustment for overtravel, and improved grips.^[2] Noting the accuracy of the Target Masterpiece, a number of police departments and the FBI soon requested the same revolver with a four-inch barrel and a Baughman Quick Draw front sight. The result was the K-38 Combat Masterpiece. The major distinction between the K-38 Target Masterpiece and the K-38 Combat Masterpiece is the barrel length and the front sight.^[2]

In 1957 the K-38 Combat Masterpiece was renamed the Model 15 when all Smith & Wesson revolvers were given numerical model numbers. (The Military & Police and the Target Masterpiece were renamed the Model 10 and Model 14 respectively.) The model number is stamped on the frame behind the cylinder yoke, so it is visible (only) when the cylinder is open. A number of production and engineering changes have been made throughout the years, some of which are noted by a dash number suffixed to the Model number (15-1, -2, -3).

Over the years the Model 15 has been produced with several barrel lengths, with 4' (standard) and 2' (1964–1988) being the most common. In 1972 S&W released a stainless steel version as the Model 67. In 1997 the hammer and internal lockworks were modified from an on-the-hammer firing pin / internal hammer block to a floating firing pin / MIM flat hammer, and kept the hammer block that, unlike a transfer bar safety design, moves up with the trigger pull. The hammer hits a transfer bar, transferring the strike to the firing pin, while the block in a hammer block system moves down with the trigger pull, unblocking the hammer from the firing pin, allowing the hammer to strike the firing pin. These two safety systems work oppositely, but achieve the same goal of only allowing the gun to fire when the trigger is pulled all the way.

The Model 15 was a popular sidearm for law enforcement and was the standard-issue sidearm of the U.S. Air Force Police from 1962 until 1992 when it was replaced by the Beretta M9 pistol.^{[citation needed]}

Production of the Model 15 was discontinued in 1999 when Smith & Wesson was purchased and reorganized, although a couple limited run 'Heritage Series' models were released in 2001 and 2002. In 2011 Smith & Wesson re-introduced the Model 15 (15-10) under their Classics Revolvers line, newly machined, with a shrouded redesigned barrel, and a built-in trigger lock (located just above the cylinder release thumbpiece on the left side).^[2]

Military and police usage[edit]

As the 'K-38 Combat Masterpiece', this revolver was first purchased in 1956 for the Strategic Air Command Elite Guard of the United States Air Force. From 1960 to 1969 the Air Force bought large numbers of Model 15–1, 15–2, and 15-3 revolvers with a 4' barrel. The only distinctive markings are 'U.S.A.F' on the left side of the frame. Originally all were blued, though some were reparkerized while in Air Force service.^[2] The Model 15 was the standard issue sidearm of the U.S. Air Force Air/Security Police from 1962 until 1992. It was issued to security personnel in other branches of the U.S. armed forces, including the Naval Security Forces.^[2]

The Air Force issued two types of .38 Special duty ammunition for the Model 15, originally the M41 .38 Special Ball (full metal jacket) cartridge, or the later-developed Caliber .38 Special, Ball, PGU-12/B High Velocity cartridge. The M41 was a low pressure cartridge rated at 13,000 psi, originally designed for 158-grain ball ammunition, but loaded with a 130-grain FMJ bullet. The PGU-12/B, issued only by the U.S. Air Force, had a greatly increased maximum allowable pressure rating of 20,000 psi, sufficient to propel the 130-grain FMJ bullet at 1,125 ft/s (343 m/s) from a solid 6-inch (150 mm) test barrel, and 950–980 ft/s (290–300 m/s) from a 4-inch (100 mm) revolver barrel.^[4]

The S&W Model 15 revolvers were replaced by the Beretta M9 pistol in 9×19mm caliber beginning in 1985, with complete turnover by the early 1990s.^[2]

In addition to military use, the Model 15 was issued by many police departments across the United States as well as various federal law enforcement agencies.^[2] In 1972 S&W produced a stainless steel version of the Model 15 which it termed the Model 67.^[2]

Users[edit]

The LAPD's Model 15 revolvers (and department issued Model 36 5-shot, 2-inch barrelled snub nose Smith & Wesson revolvers for detectives, plainclothes, undercover and other officers' off duty carry) were modified to be fired double-action only. This was accomplished by the department armorer who ground the full cock notch from the hammers. Officers were then trained to shoot combat style without ever cocking the weapons. This change was likely the result of unintended injuries and/or property damage, and of litigation against the LAPD after officers had cocked their weapons only to have them discharge inadvertently, possibly as a result of physical attacks or having been startled in the course of searching for suspects. In lawsuits, the principle of res ipsa loquitur was easily affirmed because 'an inadvertent weapon discharge is a negligent discharge'.^[2]

Overland Park Police Department (Kansas) used the revolver before going to semi-automatic Beretta 92 pistols.

Today, Smith & Wesson is mostly known for revolvers and their growing line of M&P pistols. Despite the rapidly growing popularity of these polymer-framed striker fired semi-auto pistols, there’s also a lot of buzz around the former metal-framed S&W pistols that were discontinued a few years ago.

Prices on the used market for the so-called 1st, 2nd, and 3rd generation S&W pistols are still affordable, but have been rapidly rising over the past couple of years. These pistols are usually tough, reliable, and excellent shooters. If you happen to run across one for a good price, now would be a great time to snatch it up.

The trouble with that plan is the absurdly confusing system that S&W used to assign the model numbers for these pistols. Today, their M&P pistols follow a pretty logical formula. I carry a M&P9c — a compact 9mm. Makes sense, right? Well, the 3rd Gen equivalent of that pistol is the 6904. But if it was made before the late 80’s, it would be the 2nd Gen version — the 469. And the single stack version would be the 3914, which is virtually identical to the 908. Confused yet?

Unless you’ve committed these models to memory, looking at the numbers stamped on the slide of an old S&W pistol in the case at a gun shop or an online ad doesn’t really tell you much. Even if you ask Google for some help, you might have to wade through a multi-page forum thread to get a straight answer.

Well, believe it or not, there is some logic to the old S&W numbering system, it’s just not particularly intuitive. So we whipped together this S&W semi-auto model number quick reference chart to make it a little easier for you the next time you misplace your S&W decoder ring.

Our chart covers most of the regular production models for the discontinued Smiths chambered in major service calibers. There are a few less common ones out there, but these are the pistols you’re most likely to run across today. Even with the chart, there might be a few confusing details about the numbering system, so keep reading for a little background info on each “generation” of S&W autos.

1st Gen Pistols

The first S&W semi-automatic chambered in a service caliber was the Model 39, which first saw the light of day in 1954. The aluminum alloy-framed 9mm pistol had an 8-shot single-stack magazine, a 4-inch barrel and a traditional double action/single action trigger with a slide-mounted safety/decocker, similar to what many people are familiar with from the Beretta 92 series. The Model 39 was developed as a potential replacement for the U.S. Army’s M1911A1. The Army declined to adopt the Model 39, but the pistol was a commercial success, and was even used by a few police departments as one of the very first semi-autos carried by American law enforcement.

In the early 1970s, S&W released a version of the 39 that used a double-stack 14-round magazine dubbed the Model 59. Together, the 39 and 59 are considered the “first generation” of S&W semi-autos. All of the following S&W 2nd and 3rd generation 9mm pistols are essentially derivatives of these two and in many cases, their model number provides some clue to that origin.

2nd Gen Pistols

In the late 1970s the S&W models 439 and 459 were released, which are considered the first of the second generation pistols. These were basically the 39 and 59 with a few small changes and the number “4” added to the begining of the model number. Steel framed versions of these pistols followed, available with either a stainless, blued, or nickel finish. Blued and nickel model numbers start with “5” (539, 559) and the stainless steel models start with “6” (639, 659).

In the mid 1980s, S&W released two alloy-framed compact versions of the 59 series; the 469 (blued or nickel finish) and 669 (stainless finish). Establishing the form factor that the third gen compacts would follow, these pistols had a 3.5-inch barrel and 12-round magazine.

Around this same time, S&W also began producing their first .45 ACP pistol — the model 645. This was a large frame, single stack pistol with an 8-round magazine, 5-inch barrel, and DA/SA with slide-mounted safety/decocker just like the 9mm pistols. There is one variant of the second gen .45 pistol — the single action only model 745, which was a special limited run intended for IPSC competition shooters.

I hope you caught all that because here’s where it gets complicated…

3rd Gen Pistols

The third generation of S&W pistols started hitting the market in the late 80s. They can be easily spotted by their four-digit model numbers. S&W continued the numbering trend they had started on the 9mm pistols — the 3900 series are full size and compact single stack pistols, the 5900 series are double stacks, and the 6900 series are compact double stacks.

Third gen pistols in other calibers are much easier to remember. The 4500 series is for .45 ACP, 4000 series for .40 S&W, and 1000 series for 10mm.

So, looking at the first two digits of a four-digit model number from a 3rd gen pistol, we can know the caliber, and if it’s a 9mm, we might also know the frame size. The rest of the info we’d need is in the second half of the model number.

The third digit indicates one of nine possible combinations of action type and frame size. Most S&W autos are DA/SA, but not all. Some are double action only (DAO), and a few were even made with a slide-mounted decocking lever and no external safety (similar to what you’d find on a Sig P220 series pistol). Each model series has a frame size and barrel length that is “standard” for that series, which we’ve listed on the chart. The third digit will tell you if a given model is the standard size, mid-size, or compact.

The final digit in the model number indicates the frame material and finish. Frames are either steel or aluminum alloy and the finish is either blued/black (sometimes with a nickel plating), or stainless/silver.

Exceptions

What makes this complex system frustrating to follow is that there are multiple exceptions to the product “codes”. Some are pretty easy to figure out like the “value” series pistols. These were budget versions of the third gen pistols that lack some of the finishing touches of the standard models and have a three-digit model number. The first two digits reflect the caliber (9, 40, or 45).

The Chief’s Special pistols are also easy to spot, like the one in the header image of this post. They are single stack, sub-compact variants with a “CS” pre-fix and they’re some of the most sought-after 3rd gen pistols on the used market. There’s one model each chambered in 9mm, .40 S&W, and .45ACP called the CS9, CS40, and CS45 respectively.

Besides these obvious exceptions, there are a few sneaky model numbers that look normal but don’t follow the numbering trends. For instance, the 6906 should really be the 6903 — a “6” for the final digit normally means stainless steel, but the 6906 is an alloy framed pistol with a silver stainless finish.

The compact .40 S&W pistols can also be confusing. Most are double stack, but a few single stack versions were made. The model 4040PD in particular breaks multiple model numbering “rules” and seems to have been given its name arbitrarily.

S&w Combat Masterpiece

Letter suffixes are another detail to watch for. A couple of letters tacked to the end of the model name might mean something minor like a new finish, but they can also indicate major changes like the “TSW” (Tactical Smith & Wesson) series of pistols which indicate the addition of features like improved sights and accessory rails. Sometimes, the TSW pistols were built with a completely different frame size and barrel length than the standard model.

Some of the oddball model names come from pistols developed by S&W’s in-house custom shop, the Performance Center. To keep things simple (relatively speaking, anyway) we didn’t include these and other obscure models in our chart. If you want more detailed information on any of these models, I highly recommend picking up the Standard Catalog of Smith & Wesson which was a huge help in verifying the info for the chart.
