if the gun is stainless steel, this is found ,all too often on MOST makes and models, nature of the beast. Any and all steel, "cut" or hand fitted may have edges that are and can be sharp, as well as the infamous ,Ruger Mark I,II, III target and their "can opener" front, reverse cut (undercut) sight blades, will open up any fingers, hands and slice any make or model of leather holster....GOOD luck. part of the 'learning curve'.................the rear of the 22 semi autos with the 'steel' frames, and the close, tight fit of the mainspring housing assembly into this 'slot', is another "eye" ( finger& hand) opener................yes, care and attention must be noted.............
