Both of my Kimbers are a few years old, one is a play gun and the other is my carry piece. I havn't had any problems with either, but I'm about to start replacing MIM parts with machined ones just as a preventative measure. The triggers break pretty clean at around 3 1/2 lbs and I'm happy with that. Both have Wilson slide stops and the rest are original parts. I guess first on the list is the FP & FP stop, extractor and ejector. That's not a biggie. The hammer, sear, and disconnector is a little different. I'm wanting to know who has had what kind of luck with drop-in trigger components. I've read that if you use all Brown, or all Wilson, you'll get a drop in job and all will be well. C&S looks to be a little pricey, even with my dealer pricing at Brownells, so what do you guys think. What will give me the best results? I'd rather stay away from having a smith fit everything, but if that's the only way to insure reliability, then I'll do that. Just trying to get the most bang for the buck.. Literally...

Nothing is truly Drop in but Cylinder and Slides Trigger Kits are about as Close as you can get

Nowlin kits i have used have also dropped in but the last one i sent back to brownells as it was Rough

Do forget the Mag Catch and lock they are MIM also


Everything you can fit if your uncomfortable have the smith do the Trigger Kit or inspect it after your done..

You also might need a new Thumb safety to fit to the new triger Kit

I agree and so do all my 1911's I always use C&S ignition kit at the least. The drop in most any 1911 better then the originals.

First, the extractor & the firing pin are machined part and not MIM.
Second, yes, C&S is making very good ignition parts but others like Nowlin & the like have good parts also (you have to buy the prepped ones for better fit & function).
Last, I don't think you should waste money on every MIM part in your gun. If I were you I would replace:
Hammer
Sear
Slide stop
Mag catch.

1/4 of Kimber parts almost MIM lol. yet they are in a non stess area. I can't say i like MIM parts. but they do work in guns pretty good.

Thumb Safety is a stress area and they are MIM .

some say its not but if you ride the safety it sure is a stress area

How many Thumb Safety have you ever seen broke?
I rest my case!
Actually quite a few Mostly Kimbers Couple of Springers and the joints for the Ambis on Colt and Wilson.. Seems Kimber has got that fixed now though haven't seen one in last 2 years or so
