My two cents. I think Kimber's really are great, 700-800 dollar guns. The slide, barrel, and major parts are well made. It's the garbage MIM parts that do them in, and yes, the magazines are pure junk.
I have only one Kimber magazine. It runs in my Custom II, but, it jammed my Detonics. The
mouth of the magazine seems to have warped outward, and it locks the gun up.
Wilson mags, no problems.
I think the major problems are when Kimber tries something different, and adds 400-600 dollars on top of the original gun price. People expect them to run like they should for that amount of money. Kimber doesn't test their guns, I guess, like other custom builders, and, they turn out stuff that doesn't work every once in awhile.
I think the vocal nature of the Kimber protests is due to the COST of the guns, and their reliability.
I bought a Custom II to build a .45 Super custom on, and I pretty much replaced everything that counted with Ed Brown parts, most of these forged. Likewise magazines, etc.
1911's have been around for awhile, and, the quality parts are well known. Putting them together in a gun isn't that hard. It's when you try and use mediocre parts, and charge
premium prices that people go through the roof.
I missed Dan Wesson. They now are charging Brown/Wilson like prices for a gun that has all the good stuff in it, and, used to be a couple hundred less then a Kimber Custom.
Guess it gets to a point where what kind of life style you want to live becomes an issue, both for maker and buyer.
