Thanks for the close-ups of the disconnector. I thought I saw something but I was wrong.
With regards to the catch, the bottom part of the catch wedges between the flat spring and the hammer, right? There are 2 prongs on the flat spring. The sear sits on the left and the catch is on the right. The bottom of the catch should be between the hammer and the right prong of the flat spring.

Thanks again for all the help. The catch was in the correct place, between the spring, and had spring tension on it. Here are a few picture of the parts. There is one picture with the order and orientation of the parts. This catch looks different to me, but it is the one that came in the gun.

Thanks,

Adam

The catch looks right. The picture of the catch in the USP 45 is probably the old style.

Old style.

The hammer he sent me has the cut on the side for the new catch, is this also correct. The guy I work with has a USPf 9mm also. His does not have the cut and has the small catch. I guess it could be age. The new catch almost seems a bit wider.

hmmm...

Just a thought. I think the sear axle needs to be flush on the right hand side of the frame. It looks like yours is popped out +1/32"....could this be causing the drag?...

Other than that...I got nothin'!

Bingo. We fixed it at the shop I work in today. The hammer axle was out just a bit to far in the frame rail area. This was slightly dragging on the slide causing the binding feeling. A few passes with a file and it is smooth as butter. It was seated all the way, so not sure why this happened. It is fixed though. Thanks for all the great help. I learned a lot through this one.
