Sorry for another dumb question everyone, but Does anybody know where I can get a good ambidextrous safety for my 1911? I just need a low profile safety (the ones which're just those smooth stubs) because the safety on it now is too large and it has sharp edges which graze my holster and my hand during CCW time. Also is it model specific? Or can I just buy any ambi safety and it will fit? I have a rock island tac 1911 (.45ACP) if that helps.
