I received a USP a few days ago that was completely taken apart. At the moment everything is put together and looks correct, but it appears a sear (#23) and the impact block is not moving far enough back to lock the hammer in its final position. Every time I manually move the hammer down to the final position and press down on the impact block (towards the hammer), it will lock then.  Is there any more sears or other parts in general that could be the problem?

Any help would be appreciated.

Thanks in advance.
