First off, this is not a USAF revolver but I wanted a Model 15 similar to the ones I carried as a SP.
I bought this Model 15-2 but it didn't have the correct target trigger and hammer. One of the forum members here was kind enough to sell me a really nice set for a fair price. I just got them installed today.
With a little banging around and some holster wear, this will match the ones I carried.
