I'm very happy to say, I have never had an issue with any of five Kimbers.
With most 1911's, I feel they come with too strong a recoil spring. I clean them, rack them until they feel smooth, shoot and leave them set with the slide racked back for the first month or so.
I change the spring wt up or down until the arch of the ejected case is consistant at about three to four feet.
If your shooting light loads reduce the spring wt. Shooting +P's increase the spring wt. No one recoil spring works with all loads.
Wilson sells a kit of various wt springs in a roll up bag. Play with the spring wt.
This is important with most semi auto pistols. You can tune a Glock the same way.
Ejected cases need to reliably clear your shoulder, not eject to infinity & beyond!
Early Hi Powers used to eject straight backwards into your face if the recoil spring was too strong...
I bet 80% of the Micro 9 issues could be fixed with a lighter recoil spring.
