I tried my 9mm Wilson ejector in 10mm Kimber. And guess what, FTFs went away. I suppose that OEM ejector was too tight, not allowing the round to slip under it thus not chambering the round. I only ran 20 rounds without a hiccup. Before the swap it would FTE almost once or twice per mag. It rarely got through a mag or 2 without FTF.
I have tried different mags, ammo recoil spring, full size rod, GI rod, polish the feed ramp etc. Each time FTF were less frequent but still not able to get through the mag. The ejector change never occurred to me until this post. SO BIG THANK YOU JoeG
I must had waisted 600 rounds over last 4 years to figure this out. Almost gave up on the pistol.
Again shame on you Kimber
