The man wondered it was him since these small slide guns are fast and violent and susceptible to stoppages with improper technique.
The gun would failure to chamber several times on each and every compact and full size mag used. Wilson 47s, Kimbers or Metalforms.
It was destined to be imprisoned in the used section of a glass case in Missouri. I brought it home. I know very few people carrying 3" guns so I rarely see them. But what the hell.
Tore apart and checked. Used a Manson finished reamer and headspace gauges. Again metal came out. Lengthen the free ore or leade and polish.
Pulled extractor. Tension was fine. Cut the gap from the standard Kimber .069" to .073". A little shorter than the .075" I do to the full size guns. Cut the bevel and radius the bottom. Then polish and reblued with Brownells 44/40.
Wanted to slow the slide and violence of action. Usually use EGW oversized square bottom firing pin stops but after using a few hammers and Sears of Harrison Design I went with his small radius but three angle surface firing pin stop. His parts are beautiful works of art.
The Harrison stop was perfect fit side to side in the slide and flush with the disco rail of the slide. So far no fitting. Perfect fit in the firing pin stop notch of the Kimber extractor and no clocking.
I did have to relieve the two cuts to fit and clear the ejector. Re lie with 44/40 on the cut surfaces.
New Wolff inner and outer recoil spring on the Kimber recoil guide rod assembly.
Edited and ADDED info. Without shortening overall length, rounded over that flat area and radius we the edge on the rear side of the disconnector. The slide seemed to stub here pretty badly. I increased the radius of the disconnector/loading rail but rather oblong slightly ramping it to the rear till the slide would go forward over the disconnector much smoother.
200 rounds without any issue. Smoother. Less violent. Less muzzle flip. Strong hand weak hand or both hands. No issue. With me or the owner when he flew in to train this weekend. It got shot more and will now be his daily carry! Saved from the glass display case in the trade in department.
I thought that was going to be a "it followed me home story" and I gave it a good new home. But good job on helping the guy out.
