I have a recent (2000) Lightweight Commander that runs fine with hardball but fails to feed on the last round with hollowpoints. This occurs about a third of the time. I'm using all factory ammo like Federal Hydra-Shok, Speer Gold-Dot, Winchester SXT etc. What happens is the last round will be pointing up with the rim still in the magazine. Sometimes it will get further and get partially into the chamber. I first tried a variety of magazines. This doesn't seem to make a difference. I mostly use the Wilson/Rogers mags. I tried a Chip McCormick Power Mag recently and that seemed to help a bit but still got some FTF's. I have also tried several heavier Wolff recoil springs (20-26 lb) in place of the factory spring but this doesn't help. I sent the gun to Wilson's and had a reliability job done. This includes throating the barrel, polishing the chamber and adjusting the extractor. This didn't change anything. I then sent it back and they rechecked it. Still had FTF's. I recently checked the extractor tension and it was much greater than on my Kimber Custom so I lightened it. I'm going to check and see if this helps this weekend. I've been trying to get this resolved for several months and I'm not sure where to go with it. Otherwise I like the gun but if it's not reliable it's not much good to me. Suggestions?
