Welcome aboard!

That’s a post-war K-22 Masterpiece. The military used S&W Victory revolvers in WWII (.38 Special), not K-22’s. Typical US Victory models were a fixed sight K frame with a 4” barrel. Some were made with 2” barrels. The K-22 is actually a larger gun. It was built on the same size frame, but had adjustable sights and a 6” barrel.
