Hi,I gotta know,I have a couple of .38 safety hammerless I really like to shoot but I dont like the grips,too small,I wonder if j frame factory square butt wood grips can fit,I saw one in gunbroker with whate looked like them but am not sure. If these wont work what might? Any help for my fat hands would help me hit the target,I seem to always pull it way too high. HELP PLEASE?:
