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 cal
