    What is the radius of the SR1911 frame/safety juncture vs what Springfield uses on their Range Officers? TIA

    I was told that it was .250 like Brown/EGW but the EGW i bought didn't line up very well. Most Springfields are .220

    I knew they were different, and thought SA used a Smith and Alexander contour.

    Nope. Most Springfields are a compound radius similar to a Wilson if it has a factory beavertail grip safety .

    If you want to add a beavertail to a Springfield Mil-Spec or GI model with factory tangs then you use a .220 as the tangs are narrower at the rear portion and do not blend well to a .250 as there is less material top and bottom of the grip safety pivot hole.

    I'm a BIG fan of Ed Brown grip safeties. My SR1911 Lightweight Commander's grip safety is very similar to an Ed Brown, so it's fine. When I get a few other things done to make my SA Range Officer Compact more to my liking, I'll see about having the OEM wide beavertsil replaced with an Ed Brown model.

    Really, my Loaded is a .220 and that's what my gunsmith says most Springfields are (and he shoots for them). Now my Smith and Wesson is a Wilson compound.

    Meh....

    I know what grip safeties I have fit to what pistols. But your mileage may very.
