If this is the wrong forum for this question, please re-direct me. I recently bought a JC Higgins Model 80 semi-auto 22 pistol at a gun show. When I took it to the range, I discovered that the empty magazine ejects and slides back in place easily, but when I load it with the 10 rounds, the magazine stops short about 1/2 inch of clicking into place as it should. I can push hard and it still won't go all the way in. If I move it about backwards and forwards while applying pressure, it finally snaps into place and shoots well. This is, of course, very frustrating, but I'm no gunsmith and afraid to try to do anything to it. I wondered if anyone here might have some idea of what's wrong with it? Also, I thought about getting a magazine replacement to see if that'll fix it, but don't know where to look for a reliable replacement magazine. If anyone here has any ideas, please enlighten me. Thanks a bunch.
