Revolvers make fantastic carry guns—with or without a speedloader—especially if you want a smaller pocket pistol. The Smith & Wesson 642 is an example of a trusted carry gun many gun owners use as their daily carry or as a backup gun. It has decades of proven performance to back it, making it understandable so many firearms owners trust it. We’ve spent time with the 642 as well and we’re here to share our results with you.

S&W 642 Specs

  • Barrel length 1.88″
  • Overall Length 6.31″
  • Weight 14.6 oz
  • Action Double Action Only
  • Height 4.3″

Smith & Wesson 642 Background

The Smith & Wesson 642 first entered production in 1990—in its current iteration—but the model can trace its roots back to the 1950s. The Model 642 has enjoyed years when it was the best-selling revolver Smith & Wesson made and even today it continues to retain a dedicated following. Its light weight makes it ideal for pocket carry as does the double action only trigger. There’s no denying the Model 642 is a fantastic carry option for many gun owners.

Smith & Wesson 642 Features:

The Model 642 is chambered in 38 Special and has an ultra-lightweight aluminum frame, although the barrel is stainless steel. Features of this J-Frame revolver include:

1 Enclosed hammer to substantially reduce risk of snags

4 Rated by the manufacturer for +P use
5 Ergonomically designed black synthetic grips

Smith & Wesson Model 642—Our Take

The Model 642 is a well-made snub-nosed revolver that’s impressively durable given its aluminum frame. The 5-shot capacity does leave something to be desired, but assuming the gun is being carried as a backup, that’s less of an issue. If it’s a main carry weapon, it might be wise to consider carrying a speedloader. The gun’s enclosed hammer gives it a more concealable profile while also reducing risk of snags. Its double action only trigger is also a good safety mechanism for pocket carry, although we’d still suggest utilizing a pocket holster with your Model 642.

Shootability

Taking into consideration that this is a small J-frame is important when debating shootability. It’s large enough to maintain a firm grip, although pinkies do dangle. If you’re accustomed to striker-fired or single-action guns the double action only of the Model 642 might take some getting used to, but it can be done. Comparing this revolver to other snub-nosed models does include the reality that the lightweight frame allows for greater felt recoil and muzzle rise. It’s a snappy shooter, but that doesn’t mean it’s entirely unpleasant. It shoots as expected for an aluminum frame snubby.

Accuracy

While the Model 642 isn’t a precise gun it is generally accurate. Doing a playing card drill—5 shots from 5 yards in 5 seconds—keeps all shots fired on the card, but barely. If you slow it down and take your time, your group will tighten up, but this still isn’t a super-precise gun. What it is, is accurate enough for its close-range purpose. And that accuracy is repeatable, meaning it’s a viable option for self-defense use.

Ergonomics

There’s a finger groove in the grip of the gun that not all shooters will be fans of. Personally, I dislike finger grooves, but it’s so slight on this model that it’s easy to ignore. It’s an ergonomically well-designed snubby with grips that are easy to hold onto during live fire. Re-acquiring a target is also simple once you get used to the recoil and muzzle rise. The ergonomics aren’t quite as comfortable as on a larger revolver, but they remain within expectations for this type of gun.

Value

As reliable and durable as the Model 642 is, it offers a fantastic value. The MSRP is under $600 and you can find them used for far less. It’s a solid value for what you get—a revolver that can be passed down to future generations of shooters and that could one day save your life. The Model 642 is also a good option if you’re interested in getting into the world of snubbies without investing an enormous amount of money. 

S&W 642 Pros and Cons

  • Light aluminum frame doesn’t drag down pockets with its weight, even loaded
  • Although it’s a 38 Special, it’s rated for continuous +P fire
  • Enclosed hammer means no hammer printing during carry or snagging on objects during drawstroke or use
  • Accurate enough on target for close-up personal defense
  • Snub-nosed barrel length creates greater muzzle rise
  • Double action only trigger can take time to master and is a challenge for many shooters
  • Limited five-shot capacity

Report Card

Shootability

Rating this gun for shootability against handguns of all platforms with similar barrel lengths nets it a solid C+. This is because it’s so lightweight it recoils more severely, especially with +P loads. While it’s shootable and a decent snubby, it is more challenging to shoot than many others.

B-
Reliability

This is a reliable revolver. It cycles everything consistently and hasn’t experienced any failures in the years I’ve had it. That said, when revolvers do fail it tends to be a bit more dramatic and require a greater extent of repair work. Regardless, it’s a well-made gun that’s delivered extensive reliable performance.

A+
Ergonomics

The J-frame grip angle on this gun is great for controlling the felt recoil. There’s no slippage and the gun doesn’t excessively jump out of your hands. I do wish there was a bit more thickness to its width but also understand why there isn’t. Overall it’s well made from an ergonomic standpoint, just not quite ideal.

A-
Accuracy

For close-range self-defense use this gun is accurate. However, the Model 642 isn’t as accurate as it could be, and it’s not precise at all. With some practice using the double action only trigger you’ll find your groups will improve but rapid fire can still be a bit rough.

B+
Value

The Model 642 is a fantastic value. It’s a quality revolver that performs within, if not well past, its price point.
