I have two 45 semi-auto pistols. One is my Springfield XD45, and the other is my Ruger SR1911. So far the brass that I have been running through these two pistols are the original brass that I started with.

BUT,,, I was just given 62 pieces of 45 acp brass and I have no idea what they were shot through. It is my understanding that if they were shot through a Glock (unsupported chamber) that I should not reload them and then run them through my Springfield or my 1911. Is this correct and is there a way to know if they were shot through a Glock?

Thanks guys.

Just reload em, and shoot em! As you reload them just look for cases that are damaged, no matter what they were shot in.
