So, range report. The Kimber worked fairly well, not sure if it's break-in issues but had two literal jams plus a couple of FTF double feeds and FTE stovepipes. The jams were the rounds getting stuck between the breech face and the ramp or barrel area, I'd guess - the solution was to drop the mag, re-insert the mag hard (which would then bump the bullet up), and then try to rack the slide. A couple of times the gun would be not quite in battery, and wouldn't fire. Had to tap the slide forward to re-seat it and then it fired fine. Annoying, but hopefully something that can be resolved.
Ammo used was a combination of Remington MLE 9mm 115gr FMJ, and Custom Reloading's 125gr Hi-Tek Coated 9mm, both of which have fired fine in my Glock and my friends' other 9mm guns. The jams occurred twice, once with each type of ammo - not sure if it's a mag problem or gun problem. Mags used were the stock Kimber, and 4 Mec-Gar mags I got at Reliable. Ran about 150-200 rounds through the gun, about 5-7 FTF/FTEs.
When it did shoot, it shot well! Very accurate, felt awesome in the hand, with a crisp trigger. Having my sister tag along meant that I couldn't really focus on shooting that much, as I had to keep an eye on her, but I will likely go back next week to shoot more through the gun and see how it does after the recommended 500 round break-in period.
Have to say - cleaning a 1911 is a lot more fiddly than cleaning a Glock, and I have a dent in the ceiling now. Thankfully it missed the light fixture and you don't know it's there unless you know where to look! Stupid Kimber recoil spring cap!
Also, might just be my impression but it feels like it gets a lot dirtier than the Glock does - maybe I didn't clean it as well as I did when I first got it?
