So I am still pretty new to 1911's, and have a question. I took my Springfield GI Champion out to the range yesterday. It has been a 100% reliable gun with about 500 rounds through it. After I went through about 50 rounds yesterday, the brass started hitting me in the face. And I got one stovepipe. I was using WWB, and the mags I was using were new, I just bought 6 factory Springer 7 shot mags. Could the issue be the mags?, or is it an extractor issue?, and if so how do I fix it? Thanks for any help.
