I have recently installed a new hammer bushing and removed the magazine safety and LCI.
Functions test and dry firing were good and the trigger pull felt better.
I ran into trouble at the range. The first shot of the magazine was fine, then the bolt would not fully close (out of battery) with all 9 subsequent shots,of the magazine.
I could reach up with my left thumb and push it closed, about 1/8th of an inch.
Has anyone ran into this problem?
I quess my next step would be to reinstall the factory parts, but I would like to get the pistol to operate properly without the magazine safety.

Welcome to GTO

The Recoil Spring may not down in the bolt completely, causing binding.

Take it back apart and reassemble. The parts you installed with not have any impact on bolt.

Another place to look is to see if your upper is align properly with the lower causing the disconnector to hang up on the bolt.

I install the upper with the bolt installed. This helps on getting it aligned up.

or it needs a good cleaning

Another thing to check is that the hammer is centered in the frame if not it could drag on the underside of the bolt. The new bushing should be all the way flush against the side of the hammer.

Thanks for the advice.
I will break it down tonight and check for any allignment issues.

Right on the money bullseye!
The hammer was not centered.

The older and more loose fitting bushing will allow the hammer to self-center. However, the tighter fitting hammer bushings are less flexible and can cause some rubbing in the wrong areas, creating a binding condition with the bolt. I'm glad you've got the problem solved. It is also good that you'll know in the future what to keep any eye out for when reassembling.
