I chose an old 31-1 3", blued, flat latch. I traded my 12-3 snub for it to a guy on the forum some time back. I put a pair of Pachs on it so that it fit my hand better. The old .32 S&W Long might be the quintessential centerfire handgun squirrel round. Tends to be very accurate, mild report and recoil, and doesn't mangle your meat if you're fixin' on squirrel for supper.

I'll give it to the boys to learn to shoot with before too many more years are past.
