For concealed carry or a compact backup, you want a handgun that combines small size with proven stopping power and mechanical reliability. The design should be intuitive, rugged, and easy to carry every day without compromising performance under stress.
SMITH & WESSON 640-3 is a modern production, .357 MAG revolver with a 2.25″ barrel that delivers snub-nose portability and significant ballistic capability from a compact platform. 
Design and build quality
The 640-3 is a hammerless J-frame in stainless steel with a five-round cylinder—an arrangement that emphasizes snag-free draws and fast concealment. The specimen listed SN: DKM4701 shows an excellent bore and a stainless frame with only minor handling wear, preserving the corrosion resistance and finish longevity that compact defenders require.

Ergonomics and controls
Black rubber grips provide a secure purchase while helping dampen recoil from .357 MAG loads. The hammerless, shrouded-hammer design reduces the risk of snagging on clothing during draws while allowing both double-action firing and, for experienced users, a smooth sight picture in close engagements.

Ballistics and practical use
The .357 MAG round gives the 640-3 considerable stopping power compared with typical .38 Special snub-nose revolvers. With modern defensive ammunition, shooters gain penetration and expansion options; however, recoil is sharper in a 2.25″ barrel platform, so practice with duty and defense loads is essential. The five-shot cylinder balances capacity with compact dimensions for everyday carry.
Condition and value
This example includes the original box and is described as overall very good condition—minor handling wear only—which is relevant when evaluating pre-owned firearms for reliability and resale value. Priced at $699.99, it represents an accessible entry point into a proven defensive revolver family.
For practitioners seeking a reliable, compact defensive revolver, the 640-3’s blend of stainless durability, hammerless J-frame concealability, and .357 MAG capability makes it a practical choice.
