I originaly posted this in the auto forum.
I have changed mag springs and recoil spring recently now I get my fired brass either caught between the slide and barrel or the spent round wanting to chamber itself rear first. I looked at the clinic and did not find this one. 4" 1911 with wilson mags.

Failure to eject...can be caused by one or several things. Extractor tension and short-cycle are the two more common causes. Short cycle...aka..."Short Recoil" is often brought on by too much recoil spring for the ammunition's energy level, or ammunition energy level too light for the recoil spring. 6 of one...a half-dozen of the other. In a 4-inch gun, short recoil may also be caused by the use of a shock buffer. If yours has one...take it out. If it doesn't have a buffer in it...see below.

With full-power factory ammunition...get an extra firm grip on the gun...elbows locked. If it ejects properly...drop the recoil spring load by 2 pounds and try again, firing the gun normally.

If it does...retension the extractor. If it only does it on the last round, and occasionally crushes the case between the slide and barrel hood...the extractor is "clocking" or rotating in its channel. Adding tension may cure it, and it may not. If it doesn't, you'll need to fit an oversized firing pin stop to the slide to maintain extractor orientation. May also require a new extractor if the gun is a Springfield. They've had issues recently.

Tuner,
I beleive it is the recoil spring. I dont limp wrist but did notice if I grasped the pistol a little more tightly and fought the recoil it did not seem to happen. So I need to order a new spring? I dont suppose I could cut a coil or two off this one to solve the problem could I?
Thanks,
Mike

Must be a real killer spring. For Colt Commadners and others with 4.25-inch top-ends and standard guide and plug recoil systems, I like to use a 16 pound spring for the 5-inch gun...32 coils...and trim it to about 24.5 coils. Check for coil bind and adjust as necessary.

Luck to ya!;)

Thanks, I will trim and try today.

If the spring is a heavy one, clipping it won't help much in full compression, and will mainly lighten the preload and initial resistance.
