My brother has a 1911. When he buy a new box of ammo, he runs the cartridges through the action and set aside any that seem like there’s a problem. He uses them for reloading.
I bought a Colt "Combat Target Model" 1911 back in the 90s, and it would not feed the HP I kept for defense. A gun shop told me it needed to be throated. Magazine writers always wrote about how great 1911s were. They are all hype because they served the Military so long. They were using hardball ammo in combat, and that is what it was designed for back then.
