Can a standard 1911 grip safety be fitted to a Sig 1911-22 ? --- GeezerD
It would be dependent, more than likely need to be a Series 80, Colt style cut, and then modified to accept the commander style hammer, or from a series 80 Colt Commander without a beavertail grip safety... if it's because you don't like the upswept beavertail.
A picture of your removed grip safety would be helpful, to insure it is set up to function as an original M1911...
Since I'm not sure, exactly what you have, is it a standard Sig 1911 with a .22 conversion unit, or a purpose built .22?
I know, that I have a "Colt" marked 1911 style .22, made for them by Walther. I have replaced some of the "cheap original parts", the thumb safety, mainspring housing, and rear sight with Colt OEM which required some very minor fitting, and grips with some OEM Walnut Checkered from Springfield Armory.
