    Had a new extractor installed on Kimber Pro Carry II. Original was loose. Went to range; still had 4 casings to the head out of 50 rounds. 230 grain, FMJ, Blazer, Aguila and Federal. Chip McCormick mags. Not fun. Then tried out new Sig 226 in 9mm. Ran 50 rounds of PMC 115 grain FMJ. 3 different mags and the slide never locked back after last round. Range gave me a couple of reloads to try. Only once did the slide lock back. :confused:

    Sounds like the extractor in the 1911 needs tuning and the Sig need new mag springs.

    If the Sig is truly new, it's a warranty issue...

    You may as well install a new recoil spring, too.

    yeah, i tried that . . .

    there's a new kimber extractor in there too. when i first got it, it wouldn't go into battery sometimes. new extractor solved that problem, but i still get the flying casings even with the new ejector. i'll put in a new recoil spring and see what happens. as for the sig; i'll see if things improve after some more shooting. i'll try diff ammo too. my experience with other sigs is that they come from the factory really "tight" and packed with grease. my others needed a little breaking in (after a thorough cleaning).

    You can tune a 1911 extractor to drop your brass in a bucket.

    If you are getting head shots, tweak it!

    1911 extractors need to be "tweeked" more often than not. They are intended to be fitted and tuned. It is the rare extractor that just drops in and works 100%.

    P226 sounds like weak mag springs, or a damaged/dirty slide stop. Were they factory mags? It was new? Or new to you?

    try some more

    before my next session, i'll put the original extractor back in. and try a new (wolff) recoil spring. couldn't hurt to try. other than another casing to the head i suppose. i sure won't be giving up on her. as for the sig; everything's brand new. pistol and mags. i'm in calif so i got 10 rounders. each one, new in its sig package. sure wish i could have had the three 15 rounders that came with the gun. oh well. all 3 weak? possible i guess. gotta get more range time in, that's for sure.

    On the Sig, watch the thumb when firing. If it is around the slide stop, you may have to change your grip.

    On the Kimber, if the original extractor would not let slide go to battery, then don't put it back in. As Cane says, the extractor can be tuned to drop all rounds in a bucket as you fire. Also check that the ejector is not broken. (yes, ejector).

    If Cane and NGIB are saying the same thing I have learned that more than 99% of the time they are right on.

    I wouldn't put a Chip McCormick mag in my gun. I use only Wilson Combat 8rd with the polymer follower.

    The most probable cause of a slide not returning to battery (and goofy ejection) is a weak recoil spring. While 16# is the "standard" for a 5" 1911, many require a tad heavier spring to operate reliably.

    Also, I use Chip McCormick mags as my primary range mags and have had good success with them. For carry, I always use Wilsons or Tripps...

    First, get a new recoil spring installed and see if the gun is cycling properly and if this fixed your forehead brass burns.

    Do yourself a favor and go here and buy the “The World’s Finest Gun Springs”.

    ISMI Gunsprings, Made in the U.S.A.

    NOTICE: These are a few things I do to maintain my 1911s in "canebrake" running form. IF YOU ARE NOT COMFORTABLE DOING THIS WORK, DON'T! And as with any modifications, baby steps, make small changes only. You can take more material off, putting it back on requires an entirely different skill set.

    Most extractors sold, come rough and not polished or prepared. The following graphic shows the area to check and tune the extractor hook.

    [​IMG]


    The next tweak takes time and patients to provide you with a successful outcome. DO NOT take short cuts!

    Remove the slide and take out the barrel. Take a LIVE round and slide it under the extractor hook and into position on the breechface. Make a mental note of the extractor’s tension holding the round against the breechface and if the round slid smoothly into place.

    If the appropriate prep has been made to the extractor, (see above) the round should slide up the breechface with a smooth, undisturbed movement. If there is an issue, see above.

    The following tests are subjective with respect to terms such as gently, moderately and vigorously shake (the slide).

    With the LIVE round still captured against the breech by the extractor hook, gently shake the slide to see if you can dislodge the round. If it falls out, the extractor tension is too light.

    Make sure the round did not move and shake the slide moderately. If it falls out or moves on the breechface your extractor tension is about right.

    If it doesn’t move or dislodge, shake the slide vigorously. If the round remains captured your extractor tension is too great.

    Depending on the results of this test, you may need to adjust the extractor’s tension. If so continue with the following:

    Remove the extractor from the slide and inspect for any visual defects.

    For tension adjustment, place ~ 1/2" of the extractor tip into the extractor channel and apply pressure to slightly bend the extractor. Baby steps, a little goes a long way! See below.

    [​IMG]

    After each tweak, run at minimum of two mags and note where the brass lands.

    If it falls where you want it to, you're GTG.

    If you want it to fall elsewhere, start over and tune to your target LZ.

    will do

    was going to try the old extractor with new wolff spring just to see if the problem was always the loose ejector and original recoil spring. bottom line, i'll tweak the extractor and keep on trying until this works. that kimber looks too good to give up on. it's a bit aggravating, but i see it as a chance to learn more & do more.

    i know i'm not riding high on the sig. i've got smaller hands and that was the first thing i checked. i'm really hoping that the last round i tried (where the slide did lock back) is a good omen. i've given the mags a good cleaning too. couldn't hurt.

    Much better day

    First, a big thank you to everyone who posted advice, help, suggestions. The Kimber: Tweaked the new extractor & put in a new recoil spring. 50 more rounds; no head shots. 3 casings grazed the top of my head; but it's never been this good before. The Sig: Broke down everything; cleaned with generous amounts of MPro 7. Then some CLP. 100 rounds; no problems of any kind; the magazines locked back as they should. Then, 50 rounds in my M&P .45. I had just installed an Apex sear. The trigger pull is MUCH better now.

    I've attached a pic from today's session. The target shows my last 50 rounds of 9mm with the Sig 226. Federal 115 grain, FMJ, distance 25 feet.

    Again, THANKS to everyone.
