I like my Kimber's.. I have two pre-series II Kimbers and have added a Grand Raptor II (internal extractor)to the mix recently.
My two Compact (Compact Custom & Compact Aluminum) are both Great shooters for 4-inch barreled guns. They will feed about any ammo and I have never had any issues out of either of them. They are accurate as I can shoot and a great carry size firearm. However, I do change out the recoil springs (Wolff XP for 4-inch) every 800 rounds or so in the 4-inch guns just in case.
I hope to shoot the Raptor II soon to see if the Gen II gun will act the same as my other two. I know that they all have MIM parts in them but that is "ok" for now. I have only ever had one MIM part fail and that was in a Colt gun. I do hope to get an Ed Brown Kobra Carry soon... but I want to see what Phillip at Goodlettsville gun shop can do on a custom .45 first. My next .45 will not have MIM parts so that leaves Wilson, Ed Brown, Nighthawk, and a few other custom builders in the running.
