i saw this same problem on here the other day and tried to help diagnose with some little trouble shooting steps.
my good bud from arkansas purchased a new pro carry kimber, and ill be darned if he didnt call me with the same prob.
he said that its still fairly new, maybe 200 rnds, and it has had the same failure bout 10 times.
it extracts fine, ejects good, but some times it dont go bang. when it stops, he notices that everything looks good except it stops 1/8-1/4" short of battery. he says that it is so close to completing a cycle, he can just shake the gun and it will snap into place. or very slightly push it and hes off and running again.
we live 200 miles apart so im trying to help him over the phone.
in his case, i dont think the issue is a tight chamber because i told him to try to recreate the condition, without rounds or magazine in place.
i suspected just overall close tolerances in the barrel link and lockup lugs locations and length. you know .0002 here is good, .0002 there is good, but you know, .0002 and .0002 makes .0004 if combined just right (or should i say just wrong).
i told him to try it without the mag, and let the slide go forward in a controlled manner, MUZZLE POINTED UP. then the same, slow controlled manner, MUZZLE POINTED DOWN.
this is the same test i was telling someone here to do the other day with the same prob, but it wasnt the case with his i guess.
but my buds gun would hangup, empty, when he tried this with the muzzle down, but not when pointed up. and when it occured, slight pressure on the end of the barrel would release it. as would slightly pushing forward on the slide.
to me, this says the tolerances are so close that when the muzzle is pointed down, gravity holds the barrel in the forward and upward most position, short of locking lug engagement, and causes a wedge condition just before battery.
this makes me think that a next size longer barrel link would fix the prob, but its so close, it would be trial and error for me to re-link it, and like i said, we are 200 miles apart.
i told him to check his recoil spring and to watch to see if any coils appear to compress before the others and he said 2 coils near the middle of the spring seem to collapse almost completely before the others even get close.
i told him to buy a 20 lb wolff, for a commander with the .330 full size guide rod, and that i think it will mask the close tolerance issue till the gun is properly "worn in"
shouldnt this work since it requires such little force to push it into battery, and seeing that he most likely has a spring issue anyway?
sorry for the long read, i wanted to be thorough.
