So I am REALLY confused here. The first picture is of my 908. The second picture is of a 3913 "Lady Smith". The third picture is off the hogue site of a 908 with hogue grips. What I am not understanding is the retaining pin. On my 908 and the Lady Smith it is at the very bottom right. However on the 908 on hogues sight it appears to be quite a bit different. Can someone explain to me how these things actually work?
