I just bought springfield 1911 GI .45 Mil-Spec.

It has the low profile sites, and is a replica WWII 1911.

I have been getting stovepipe jams consistently even w/ proper cleaning and maintenance.
I have only shot around 2,000 rounds through the pistol since i bought it a year ago, however, every 20 rounds or so it will jam w/ a stove pipe (the shell remains stuck to the ejecter on the lower side near, sticking straight out of the chamber (hence the stovepipe).

If anyone have suggestions on what the problem could be, or if i should just take it to a gunsmith and have him shave my magwell and lip on my barrel?

Any help appreciated.

Have you been to the 1911 forum? I think the url is www.1911forum.com but I am not perfectly certain, do a Google on 1911forum and it should find it for you. Check their older forum area, as I am pretty sure that I saw this same problem over there.
My second question to you is what kind of ammo are you using? Soft (low power) ammo will stovepipe more often than the full power stuff if I remember correctly what was said there.
May God bless,

Simple things to try:

1) Have another shooter try it. (S)he must be skilled with the 1911. This test eliminates most mechanical errors.
2) If there are still errors, switch ammo.
3) If there are still errors, swtich magazines. Try Colt factory mags.

Gary is Correct: You didn't mention if you were shooting two hands, (combat) type shooting or single hand (Nat Match) type shooting. The malfunction that you describe can be caused by an inability to lock the "strong" hand wrist or elbow.

A person who is well experienced with this gun will know how to do this, and if proven correct, will be able to explain it to you.

In either case, (Combat, or Nat Match) the strong hand must be extended to a degree that it is very stiff. You can check this in the recoil. When fired, the gun should not ride much out of your normal shooting position, and should return to the position that the gun was fired from.

Extractor tension too light...Extractor hook too long from tip to wall where the
case rim contacts. Should be .032 to .035 inch. Ejector out of spec...combined with extractor tension allowing the rim to ride over the top of the ejector.

If it happens mostly on the last round, and occasionally crushes a case in the port or locks the slide and leaves the empty laying loose in the port, check the
extractor for clocking...rotating in the channel.

If you've got a heavier than standard recoil spring in the gun...put the stock spring back in it. 16 pounds is a gracious plenty. If you've got a shock buff in the gun, take it out and try again...

Thanks for the help.

I often am aware of my own "limp wrist" problem. It happened on my friends Sig (whose manual warns of limping it and possible jams)

As for the ammo, i shoot nothing but FMJ Winchesters, and the occasional Winclean. Always 230gr, i already tested hydrashocks and other lower grain bullets, which didnt seem to feed well the first day i got my gun, so i havent used them again.

Well thanks for the help, ill go look for that forum too. Maybe they have some other helpfull hints.

by the way, in case you didn't know, clocking of the extractor is it rotating slightly in the channel due to a poorly fit firing pin stop.

I've had this problem with my springfield, my firend had it with his. It's worth checking.

Just FWIW...I don't buy into the "Limp-Wrist induced Malfunction" Theory.
If the gun hangs up with a limp grip, it's probably oversprung. Other
things factor in too, but that's the first place to look.

Most kill or be killed situations happen at powder-burn distance, and you
can't bet on having time to get the perfect, locked grip on the gun...You
can't even bet on havin' time to get a two-handed grip, since you may have
to fend off a knife or blunt weapon attack with your weak hand while you
back up and reach for the gun...If the gun won't run with a less than perfect grip, how ya gonna trust a snake like that?

Just my 2% of a buck...YMMV

Luck!

A few things you might check. One is the breech face, it maybe a little rough and needs some smoothing. I replace ejectors on quite a few guns to the a longer ejector. This normally helps. You might also check the ejector you have and see if the top angle of it needs to be slightly beveled to help flip the round out the top instead of letting the round roll up in get caught in the top of the slide. :D
