I had my Norinco HP9-1 out yesterday for the first time and ran five Federal 2 3/4" 1 oz. magnum slugs through it. I found that I couldn't load any more than three shells into the magazine tube. The fourth would just barely NOT fit. I didn't have any other shells to compare length with. Now I just tried it with Winchester 2 3/4" 00 buck and it fit four just fine, though the fourth left extremely little wiggle room. Are the Federal magnum slugs just that much extra longer or is there something wrong with my gun? Would I benefit from a +1 extension?
