MIM Parts and breakage
Go to
www.1911forum.com re MIM parts in Kimber. These include Ambi safety lever, Slide stop/takedown lever, most of the trigger and sear parts, and other internals, rear sight. On my Gold Match, my rear sight broke twice, Ambi-safety lever bent. Most good smiths will recommend replacement of MIM internals before they do a trigger job because the parts are soft and can break.
As to being hard on guns, I shoot about 1000 rounds of pistol/month. 300-500 rounds of rifle. So far
Sig 226 -- 2700 rounds. No breakage, no FTF, no FTE
Glock 34 -- 1500 rounds. One or two FTE (stovepipe), no breakage
Glock 23 -- 2000 rounds. One FTF. No breakage.
HK p7 -- 1500 rounds. No breakage, no FTF, one FTE (probably bad ammo)
HK USP .45 -- broken firing pin at 1200 rounds damaging frame. Whole gun replaced under warranty. Now there appears to be problem with out-of-round chamber.
HK USP .40c -- slide cracked at about 1200 rounds. Slide and bbl replaced under warrnaty
AR15 -- 4000+ rounds. No breakage. Base over jam perhaps once every thousand rounds or so
SW 617 -- Rear sight replaced under warranty, and bbl gap reset, forcing cone trued. Other than that 6000 trouble free rounds.
Kimber-- Where do I begin? Arrived NIB with lots of metal shavings inside. Jammed every 15 rounds or so, even after 500 rounds of ball "break-in". Would not shoot to point of aim even w adjustable sights maxed out. Bad creep in trigger. Kimber ended up replacing the whole gun.
Muzzle flip and HK USP:
Muzzle flip is relative. Muzzle flip on my P7m8 is about 1.5" in rapid fire. USP has high bore axis, muzzle flip closer to 5" in my hands. Recoil is mild due to double spring. All-steel 1911 about 3" in my hands. If HK USP really had low muzzle flip, people would be using them in gun games instead of 1911. I don't know any serious IPSC or plates gunners who use USPs.
It is a good $550 gun. Feeds everything. It just has its shortcomings, like any firearm. Bad DA trigger pull, relatively high bore axis, and some reliability problems as noted.
