I recently purchased from a CGN member a Norinco 1911A1 which has had several upgrades for competition. These include Ed Brown matched hammer & sear and trigger, all stainless, releasing at 3.5#. Again in stainless, Ed Brown slide safety; flat hammer and grip safety. The barrel bushing is a Micro match bushing, and the recoil spring has been replaced. Gun is equipped with Williams Firesights, and very nice burled wood stocks. Magazines are Wilson Combat 8 round stainless. Very nice piece.

The issue: The hammer/sear setup appears to have been modified so that the gun will fire when the slide safety is engaged. With the gun cocked and the slide safety in position, when the trigger is pulled the slide safety drops to disengagement and the hammer falls. Grip safety works perfectly and the issue does not occur if the grip safety is not squeezed in firing position.

I have not attempted to test the issue with live ammo at this point.

Can this be remedied? I suspect my Range Officer will be somewhat unimpressed with the setup as is and really would prefer a functioning safety.

PM to Publican or reply here - any suggestions gratefully received.
 
First check is the thumb safety fully inserted? If it is not you can get tis effect. When the thumb safety is engaged the slide is locked in position, and if fired in this state damage to gun and shooter may be expected. If the thumb safety is properly installed and still allows the hammer to fall, it must be replaced as soon as possible.
 
The question has to be...Who did the work?
More often than not, anytime work is done involving sear/hammer.
A NEW thumb safety has to be properly fitted.

IMHO. This pistol is in an unsafe condition.
Since you asked the question, I would advise taking the gun to a competent Pistolsmith.

I have returned the gun to the seller who has agreed to repair or refund my money if it cannot be made right.

Seller advised today gunsmith tuned trigger and safety now OK. Gun in mail tomorrow. Sounds good.

What Halger said.

A 1911 action is one of the sort of designs where each part relies on the previous one in the chain. And the thumb safety is at the very end of the line. So as clearances and allowable variations stack up the thumb safety ends up doing what you got.

Basically with 1911's "drop in kits" are seldom fully drop in if you want the safety to work correctly afterwards.
