Hope I'm not asking a question that has been answered before. I have a Colt pistol marked "Colt Super .38 Automatic". It was purchased new in 1949. The gun is in nearly new condition. I think that makes it a model 1911. Anyway I recently shot the last of some old ammo that was .38 super and all I find now is .38 super+p. Can this old gun shoot this hotter ammo? If not where do you buy it? None of the regular manufacturers sell .38 super ( no not+P).
