Good to know, I'll be extra careful to check the rounds in the magazine I load into a 1911.
It was fired in a 45cal gun, I've done it in purpose with 9mm and 40cal in a 45 1911, although I couldn't get the 9mm to go off. Nothing bad will happen as there is no chance for pressure to build.
And 9mm 1911 mags are the same magazine accept it has 2 ribs in the mags to keep the 9mmnrounds centered in the mag.
