Little Al Hap made them up for me,he made up some for me this past June,at that time he made up some extra sets for stock,he dosnt have them listed on his site. My firing pins mushroomed on both ends,but as Hoof Harted said welding up the slot in the hammer cant help but make for a more harmonius outcome.The ones he did for me were for the back plate cylinders,Im not sure if the gated conversions use the same F.P. or not.What I do know is Hap will know,if they are not the same I do know he can make them up for you,give Hap a call.
