On a test of my new 1911. I find that it jams every single time on ejection. I load a mag, chamber, and fire. The slide does not come all the way back to the rear and the empty casing is only parshally (1/4) ejected. ARG!!!!

What kind of 1911? What caliber?

High end tightly fitted ones require some break in...

How's the tension when you manually rack the slide?

There could be a "too heavy" recoil spring installed too..
 
My Home built 1911. No name frame and all Norinco parts. 45acp.

Factory ammo. It was lubed, just maybe not enough....I'll lube the crap out of it next time. Where can I find a lighter recoil spring? I got a norinco one in there now.

The tenshion may be too tight...I hope this is not a permiate problem....I'm so put out :(

45ACP factory - yep - try a lighter recoil spring... recommended weight for 45ACP ina 5" is 16lb. If you don't know what the Norinco is - get a 14 and a 16.

I really hope that's all it is :( I'm new to the 1911 so you guy's are a big help. I tend to get discuraged when stuff like this happends. I keep thinking I F*$%ed up on the build process some where.
 
Don't think I'm questioning your manhood, but how firm a grip do you have on the gun?

If you have too light a grip and not enough resistance in your wrists and elbows, you can absorb some of the recoil the gun needs to cycle.
 
Not sure....never thought about that...I'll make sure next time I grip it hard. I do have small wrists:redface:
 
Just a thought here....

1911 style pistols ARE simple and straightforward, however some of the parts must be fitted properly (like the grip safety) for safe operation.

If you do not have a hand-book like Jerry Kuhnhausen's "The Colt .45 Automatic, a shop manual", I would suggest that you try to find one ASAP (Ebay is a good place to look).

It is easy to create a dangerous situation....

Live long and prosper....:)
 
yeah had same problem...it was a weak mag spring..Can you try a new mag or a different mag and see if it helps?
 
How would the mag make it jam on extraction/ejection? I could just chamber one round, remove the mag and fire to see if the casing ejects and the action cycles properly.
 
well I found that with weak mag springs..I could chamber a round and it would have extraction issues..generally on the last round...Changed mags and it solved the problem. YMMV

......lap?

Lap - "Lapping Compound" - an abrasive lubricant that you insert between the two moving metal parts (ie slide and frame) and them move the metal parts so they wear in together. You then wash out the lapping compound thoroughly and things fit better.

Caution - a little at a time is the way to proceed - metal can't be put back on...

Brownells sells compound but you might also be able to find it at a machine shop that does engine rebuilds.
 
I really don't think the slide is too tight. Not at all. I' actually conserned it may be a small...very small bit too loose. I have a spring set on order. I hope that will work. Anything elese it could be?
 
I don't mean to be a smart ass, but did you fit an ejector to the frame?. I f you used an 80% frame, some have to be drilled for the ejector, and you may have missed it. Most people that sell Norinco parts kits don't include the ejector in the kit.
