I know with a 1911 there can be a world of difference on the Inside, but on the outside a Commander length appears to be the same in appearance. Apart from my 1911 ish Sig Sauer they seem to be mostly the same. Is there any reason you would not want to use your favorite 1911 specific holster for two or three 1911's. Not sure how they multiplied so soon but I really like the platform.
