Kimber Eclipse 10mm 2nd round hangs up

Morning

I'm having a bit of an issue with my new (2017) Eclipse 10mm series 1.


Gun seems accurate as it will easily shoot to a 3" circle at 25 meters off-hand.

It just about always hangs up the 2nd round fed from mag,
3rd round on feeds good but last round will sometimes not
go all the way in either.

It seems to eject the first round OK & picks up the 2nd OK
but the slide doesn't go all the way home (round about 7/8
of the way into the chamber with slide sitting proud about
3/8" of fully closing.

I know it's a new gun but I have just about 250 rounds
through it with no change to the 2nd round feeding. Have
tried Armscor, Seller & Bellot, Remington UMC all in 180 gr
though.

I did an extractor test & it seems to pass the case slide-in
test OK as well as holding a loaded round fairly securely.

Ejection runs a bit erratic with most ejection at 4-5 o'clock
& about 15 feet. Fired brass sometimes go high, or all the
way to 1 o'clock, with some going over my head. (I'm used
to my other 1911's stacking the fired cases in about a 2'-3'
circle at 5 o'clock.

Breech face is fairly smooth with no roughness around
firing pin hole. Upon hand cycling the slide the 2nd round
is a bit hesitant but usually goes all the way home.

I have been shooting for almost 60 years so have seen
a number of 1911 feeding issues so my usual starting
place is a new extractor, or at least an extractor adjustment.
Then possibly followed by a breech face polish.

I don't have another (10mm) mag to try yet but think
I will try some of my .45 mags.

In any case thought I would ask here first in case this is a
specific issue to the Kimber 10mm guns & there is
something else I should be looking at.

Thanks for any & all help

I'd lighten up the extractor tension some. IMO it should barely hold a live round. Meaning you can shake it loose without a whole lot of effort. I wouldn't refer to it as holding it securely. And just to ask, are you indexing the rounds with the barrel when checking extractor tension? You want the round right where it's going to be as if you were shooting the pistol.

If it's tossing brass all over it could be you or it could be the extractor is clocking (rotating). Or the ejector needs tuned or maybe the empty case is brushing against the next round in line upon ejection.

I'd loosen up the tension on the extractor and take it from there. One thing at a time.

It's definitely not me on the scattered brass ejection
as ALL my other 1911's toss the spent brass into a nice
tight spot (I can usually pick all the brass up without
moving)

I always check the extractor with the round positively
centered with the barrel. I also check the round entrance
just as the round is starting the rim to extractor entrance to
look for hang-ups there .

The extractor might be a tad tight, but it will securely
hold an empty case. I can shake a heavier loaded round
off the extractor with a light to moderate slide shake
(I do understand a tight extractor as I have addressed
many of those in my long 1911 shooting history)

BUT, I can't ever remember encountering a tight extractor
that ONLY effects the 2nd round in the magazine
(a tight or buggered extractor usually effects all rounds
entering the chamber)

The thing is-- it will toss brass to the same spot 3 or 4
times in a row then toss one over my head, or more
forward to the 1-2 o'clock position. Again, a misadjusted
or tight extractor usually doesn't give those 3 or 4 good
ones in a row.

If they jam with the slide open farther I can usually see
where the case is hanging up but on this gun the slide
closes far enough that I can't see in there.

I pulled the bullets from a couple of factory rounds then
re-loaded as no-powder dummies so maybe I can see
something from the bottom with the mag removed
(I t-h-i-n-k the round is just clearing the mag lips when
it jams) if so I should be able to drop the mag on a jam
without disturbing it (I hope).

I haven't played with hand loads yet as my normal sequence
is to get a gun shooting smoothly with factory rounds THEN
start playing with reloads & round OAL.

If I can't find any smoking gun (or someone here doesn't point
me to a known Kimber feed problem area) then my next move is to
probably to call Kimber to see if they will send me a new
(or hopefully improved) extractor to play with.

What happens if you just load 3-4 rounds? Will they all feed?

About the same thing- round 1 feeds OK from slide lock,
#2 jams, #3 feeds OK, usually from slide lock again.

OR #3 will always feed upon shooting #2 (IF) I can get # 2 jam
to go into chamber without removing magazine & clearing
jam.

If I load 4 rounds then # 4 will always feed OK when shooting #3.

Do you have another non-Kimber mag you can try?

Morning pacanis

Sort of-- I have a number of good functioning .45 mags
so one by one I am going to try them. I don't have another
1911 10mm mag.

I have some Wilson .45 mags that s-e-e-m-s to hand
feed smoother than the factory Kimber 10 does.

As I mentioned above I wasn't planning on buying any
new 10mm mags until I get something working (I don't
want to buy 10mm mags that don't work if I can possibly
help it)

Morning_2

A little more info & follow up--

This morning I shot 3 full mags of .40 (180gr) & low
& behold they all cycled great with no hang ups or
malfunctions. It seems the shorter rounds are entering
the chamber at a better angle & cycling smoother.

Next I tried a Kimber .45 mag & a Wilson .45 mag.

Better but still no cigar (but maybe hope).

The Wilson still hung up the 2nd round BUT I could
easily just bump the rear of slide & it then went fully
into battery (no solid jams like the factory 10mm mag)

All spent brass from the Wilson mag went to around
5 o'clock, large scatter but at least all in the same
general direction (none over my head)

The Kimber 10mm mag was no better than the stock
Kimber 10mm mag.

The thing that still bothers me is the spent brass is all
scratched up so it sure isn't entering the chamber without
a fight.

I caught a couple of hang-ups & dropped the mag to look
in from the bottom & it looks like the round is coming out
of the mag with good bullet placement but the rear of case
is coming out & staying too low so the round is being
forced forward at enough of an angle to bind up mid case on the
feed ramp to chamber junction.

On an out of warranty or a hand built 1911 I would
usually polish/blend the lower part of the chamber entrance to
help this but on a new (somewhat expensive) Kimber I
shouldn't have to as well as I don't want to do anything
that Kimber can blame the problem on.

+1 on not doing anything Kimber can blame on you... but if it was my 1911 I'd throat it. I had a feeding problem with a new Ruger LCPII that a little throating cured right up. Sometimes edges are left too sharp.
Or you can keep on plugging away and get your break in rounds through it. Or send it back for 5-7 weeks. Ouch.

What are your cases, nickel plated or solid brass? Nickel might feed easier and naturally work on the throat.
