Recently bought a new G21 gen 4 and have shot about 350 round through it and it ejects poorly. Sometimes, it ejects straight back into my face and sometimes I get hit in my right arm. Even when it doesn't hit me, it weakly ejects about two feet to the right. I bought a case of PMC Bronze 230 grain FMJ and that is the only ammo I've shot thus far. Could this be the issue? I plan on buying different ammo, but was wondering if anyone else had this issue?
