He also shoots my .45ACP with no issues, so it goes to reason that the 9mm should function with him also. I think I have the problem fixed anyway, I appreciate the input that those gave concerning the issue I was having.
In a short-barrelled semi-auto pistol, grip and technique are of supreme importance to reliable function. If enough recoil force is "scrubbed off" by a loose hold or a limp wrist, reliability will suffer. The pistol may not fail to eject every time, but it won't be reliable.
I suggest that a small, powerful, semi-auto pistol will not be at its best in weaker hands, be they the hands of a young child, those of an inattentive man, or the hands of a less-than-fully-strong woman.
Bear in mind that I believe that any reasonably motivated 10-year-old can successfully shoot a full-size, full-weight .45 Government Model. Shorties are, however, quite a different matter.
I thought that it was a smaller version than that.
Like I said before it was probably a spring or combination of springs that were the problem
I came across this old post and wondered if you resolved the extraction issue? I have an utra carry II and mine partially extracts the fired rounds and then drops them. It does this with factory ammo or reloads. I sent it back and they replaced the extractor (since the gun was purchased new). I still have problems. Im thinking I should have bought a S&W m&p or a glock. I have run about 2000 rounds through it. I'm just trying to find out more before calling kimber again.
He did fix it with a new recoil spring,which you should replace now with that many rounds.Kimber has been known to be weak on their extractors and tuning them,they may have replaced it and a few rounds worked and shipped it.Check the tension as the begining of this thread said if it's still dropping them.
There are 2 other possible problems in this scenario I don't think I mentioned.First is a weakened mag spring but I doubt that's the issue.What may happen is a weak extractor lets the case drop a touch and when it gets to the next round,since 9s are short,the case bumps the round and the hook loses the rim.Another problem that's rarer is the extractor is too long and bumping the barrel face.If light it will keep knocking pressure off the extractor,if heavy it will break the hook clean off.Try a new proper wight recoil spring first,the shorties should be replaced pretty often and need a good hold compred to the 4"+ guns.An easy way to get more lockdown without a death grip is roll your elbows out when you get extended,it helps stiffen everything to your shoulders.
