Yes the gunsmith installed an FFT spring. Which i thought might have been the problem, so I replaced it with the original factory spring and it still has the same issue.
I tried what you suggested in the later portion of your reply and it's 50/50 if the shell is partially in the magazine or just inert in the lift until I have to push it up with my finger.
I haven't checked if the magazine is screwed in all the way yet. I'll have to do that.
