Joshua, To answer your question (somewhat) quickly...Let me preface by saying that my Kimber (Pro CDP II) was a very accurate pistol....But when I first got it, I experienced the slide locking back with rounds still in the magazine. This was my 1st 1911 and was JUST learning about them, etc...so I really didn't know how to diagnose issues, etc.
So I call them up and they ask me if I had put...I forget, maybe it was 300 or 500 rounds through the pistol first. I say "Uh...no, maybe 100-150...but..." They tell me that there's a "break-in" period and to first do that. I'm thinking jeez...so that's about $200 or so worth of ammo for "break-in"...now that brings me up into a different "tier" of 1911 which would probably be better built and run right out of the box, etc (read: Dan Wesson, which is what I originally placed the order for).
So, I run the suggested ammo through it...same issue over and over. I call them up, tell them it didn't go away...and they say "Oh yeah, it's a common issue, let us send you a 'revised' slide stop lever".....***?! KNOWN ISSUE? I JUST CALLED YOU 2 WEEKS AGO AND YOU GAVE ME THE CANNED RESPONSE OF "RUN MORE AMMO THROUGH IT". So they send me the revised slide stop which had a bit of filing/stoning on the profile...I install it and presto...everything runs like a top.
So then, as I'm learning more about 1911's...I get into the whole MIM parts thing. Now....did I have any MIM parts break? No...but I would rather NOT have them, than have them..period. That's just me. In addition, I come to find out that the mainspring housing on the CDP is made of plastic...***. So I order a new steel one from Kimber ($75...so now, with "break-in" ammo...and the cost of the pistol, we're now up to $1,350), which required a bit of stoning to get it fit properly...not an issue. The one that comes out is totally plastic junk, like a lego piece. Then, as I'm looking at the thing, I notice that my beavertail grip, also an MIM part...still has the little circle on it that was made when it was poured into the MIM mold. Just as though it was a piece from a model set I had as a kid...THIS for a 1911 that lists for $1,300? The slidestop lever....MIM....the hammer...MIM....the thumb safety....MIM....grip safety...MIM.
Then I decide to switch from a Glock 34, in IDPA....to a 1911. So I purchase a (cheaper) STI Trojan, just to use for IDPA, thinking it'll get banged up a bit, etc. I get it and the quality is SO much better than the Kimber (IMO)...the slide is like it's on ball bearings.....the general build quality is just better. Thousands of rounds later, it has never hiccuped a single time. (Granted, the MSH is also plastic on it...although I've replaced that with a oversized MSH/Magwell in its place).
Then, I decide to order a Fusion...built to my specs...This is when Fusion FIRST started building and their prices were just a bit cheaper than they are now and were only a couple/few hundred bucks more than what I initally paid for that Kimber. Well, once I got that thing...it became pretty evident what a POS the Kimber was for what I paid for it, which is why I sold it the same week of getting my 1st Fusion. It was embarassing. The Fusion is an absolute tack-driver accuracy-wise, and the build quality, is just in another universe. I have 2 now, hundreds of rounds through them...never a single failure of any kind whatsoever.
I guess something has to pay for all those Kimber magazine ads you see 3 examples of in every magazine. They just pass the cost along to the consumer, and the thanks you get are parts that are just a step down quality-wise, IMO.
That's been my experience w/them. Take it FWIW...
