Did you remove ALL of the material in the barrel block area?? I had a little hangup like that if I let the slide go forward slowly and I had left a little material on one side of the cutout area. I think the action spring was hanging up on that. It quit doing that after I went back and cleaned that up a little and works fine now, nice and smooth, regardless of how far I move the slide rearward.
I dry fire practice and sometimes just reset the trigger with my strong hand, so often I only partially rack the slide, no hangups at all now..
