Comparison FAQs

Can the 642 fire .357 Magnum?

No — the S&W 642 is chambered in .38 Special +P only. It cannot fire .357 Magnum. The Ruger SP101 is chambered in .357 Magnum and can also safely fire .38 Special loads.

Which is more concealable?

The S&W 642 is lighter, shorter, and has no exposed hammer — making it slightly more pocketable. Both are genuinely concealable in a proper pocket holster.
