So I am still shopping and planning my holster purchase for my 3" Model 65 I picked up. As I search around, I just began wondering about just how uncommon the 3" barrels are. For example, for every 100 model 19's, how many were made with a 3" barrel as opposed to the 2 1/2", 4", or 6" barrels? If anybody knows, or can point me in the direction of an answer, that would be great.
