To try to answer everybody in a single post:
I use Wilson Combat magazines, and I keep track of which of them has feed problems. So far, neither of my two mags is any worse than the other one. I have no other magazines, and I purchased these magazines a little over two years ago from the same shop that cleaned my gun and test fired it. They recommended that I replace the stock Kimber mags, so I did. The magazines hold 8 rounds.
More than 800 rounds have been fired through the gun, and I just received my order of another 300 rounds of Remington UMC 230 gr. hardball today. I will definitely shoot all 300 rounds of this ammo before making a decision as to what I will do with the gun.
The folks at Kimber told me that the gun was not designed to shoot anything but 230 gr, round nose FMJ Ball ammunition, and that Kimber would not warrant that the gun would shoot any other ammunition reliably. Also, page #25 of my Kimber Operational Manual states: "NOTE:
1911 style handguns in 45 ACP were designed to function best with bullets that have a smooth contoured nose." The folks at Kimber pointed this out to me when I called them about my feeding problems with SWCs and JHPs. What really puzzles me is that it appears that other Pro CDP II owners are able to shoot these rounds reliably.
I used to own a very accurate Colt Gold Cup, and I regularly shot 190 gr. cast SWCs with no feeding problems whatsoever, so I guess I might have ignored the warning in the manual as being typical legalese. My mistake, I guess. It never occurred to me that a premium firearm like the Kimber might be less reliable than a Colt.
I shot 200 rounds of PMC 230 gr. FMJ ammo at the range a week apart over the past three weeks (last week and the week before - 100 rounds each week). Each time, I had two FTF stoppages. Four FTFs in 200 rounds gives me a 2% FTF rate, which is excessive, in my book.
I wish I had a way to take a clear picture of the barrel hood through a jeweler's loupe and post it so that you can see what I am referring to. Maybe I'll give that another try tomorrow. It isn't real rough, but it is certainly rougher than what I would expect from a custom shop. It is the bevel between the back of the hood, and the underside -- right where the edge of the brass must pass when feeding a new round. If I was shooting hand loads, I would wonder about the crimp, but this is all factory ammo.
With an open and locked slide and a full magazine of Federal Premium 185 grain FMJ Semi-Wadcutter ammo, the first round will not feed when the slide is released. It will never feed, and Kimber tells me that the gun was not designed for use with Semi-Wadcutters. I suppose that is a reasonable position for them to take, and I would understand it completely, if everybody who owned this model of 1911 had the same issue ...
Thanks for the suggestions. I appreciate the help.
