Hopefully one of you guys may be able to give some advice. I have a combat master (MKIII)that does not like to feed the last round of just about any magazine that I put through it. I have test fired atleast 50 rounds through each of the following magazines. Wilson sentinel, Detonics factory stainless, Detonics factory blue, and 2 metalform magazines. All the detonics mags have been tried with original springs and followers and I also rebuilt the magazines with new wolf springs and new round followers from brownells. As for the feed ramp and throat they are polished and smooth. The recoil spring is also new. I have had two local gunsmiths take a look at it and even they are at a loss. The gun will dry cycle dummy rounds,federal hydra shocks or whatever you put through it but will not feed the last round when you go to live fire it at the range. This is the coolest little gun I have ever owned but I have had it almost a year and can't carry it! Any suggestions would be greatly appreciated.
Thanks
