What Reviewers Say
Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.
10 pounds 7.1 ounces and because of the heavy trigger pull this is really not suited for those who have little experience shooting.
Even though it's very small, it's just very shootable.
I've carried this the last week for pocket carry while working and it's been absolutely awesome it does come with its negatives though.
One of the big things about a small revolver is that they're very reliable with that double action trigger pull i mean when you pull that trigger it'll fire unless you have some kind of problem with the ammo.
These grips honestly are very comfortable they're the rubberized cushiony grips and i really like these grips.
Customers Say
AI-generated insights derived from customer reviews and discussions on popular gun-enthusiast forums.
The S&W 642 Airweight draws consistent praise for its carry-friendly weight and reliable operation. Owners regularly note that it's comfortable enough to carry all day, which is the main reason most people buy it.
The DAO trigger gets positive marks for simplicity: no manual safety, no hammer to cock, just a consistent pull every time. That appeals to people who want a grab-and-go defensive revolver. Build quality is generally well-regarded.
Recoil with +P ammunition is the most common complaint. A 14.6 oz gun hits back harder than heavier revolvers with the same caliber, and some owners find it genuinely uncomfortable during extended range sessions. Five-round capacity also comes up frequently as a limitation versus semi-autos.
Fixed sights draw criticism from shooters who want precision at longer distances. Holster compatibility is a recurring practical issue. The J-frame profile is common enough that options exist, but not every holster fits the 642 well. The enclosed hammer also means no single-action option for deliberate shots.
