I have been cleaning thing up a bit and getting rid of stuff I have for previously owned firearms and came across something I did not remember I had. It has the S&W emblem on the back and the number 19 to the left below that and 32 to the right. My 2" 5 screw 50's model 10 fits a bit loose and my 3" model 13 a bit tight. My 4" 13 fits in in between in tightness and the barrel sticks out the end. The others do not. I am not a snap holster fan and cannot remember how or when I came by this. Just looking for information on it.
