Here's another Dad gave me. He got it from his dad, who got it from a cousin who was a cop in SE Texas.
A well traveled example of a S&W M&P (Military and Police) 4th Change, made between 1915 and 1942. Likely still shoots good, but don’t run anything too hot through it. Find some wadcutters.
These old S&W's actions just get sweeter the more you shoot them.
It's a keeper, too. It has the marks of ownership. Don't let anybody "refinish" it.
