S&W J-Frame revolver. 5 shots, very effective cartridge.
.32 is a toy - DON’T USE IT.
The S&W 642 is a .38 +P firearm. Add a Crimson Trace Laser Grip to it, and you now have a very accurate gun, unlike the base gun that has crappy, short sights in order to not snag on anything. The 642 conceals VERY well in a pocket holster (I use Uncle Mike’s, YMMV).
