CJDOUBLETAP Posted June 7, 2009 Share Posted June 7, 2009 I have a 6 inch 2011 with 2 uppers ( 1 in 9mm and 1 in 40). The 40 upper works fine. The problem is with the 9mm upper.When the firing pin stop is in, the slide/upper drags on the frame. When I take the firing pin stop out, the slide moves freely moves on the frame with no drag. There is about 10K rounds on the 9mm upper and the problem just started during the last thousand rounds. I looked at the firing pin stop via the magnifying glass and couldn't detect any cracks. Does anybody know what the problem is or what I should be looking for to diagnose the problem? Is a firing pin stop a drop-in or a gunsmith fitted part? Thanks, Craig Link to comment Share on other sites More sharing options...
Dan Sierpina Posted June 7, 2009 Share Posted June 7, 2009 Look at the bottom of the stop. That's the only place it can drag on the frame. Link to comment Share on other sites More sharing options...
CJDOUBLETAP Posted June 7, 2009 Author Share Posted June 7, 2009 Look at the bottom of the stop. That's the only place it can drag on the frame. Ya, I thought about that and polished the bottom of the stop with a stone to take off any burrs it might have and it still didn't help. Thanks for the feedback.

z40acp Posted June 7, 2009 Share Posted June 7, 2009 Is the firing pin stop rubbing on the ejector? Link to comment Share on other sites More sharing options...
CJDOUBLETAP Posted June 7, 2009 Author Share Posted June 7, 2009 Is the firing pin stop rubbing on the ejector? Maybe, but why would it just start now? I'll check after today's match... Link to comment Share on other sites More sharing options...
mpeltier Posted June 7, 2009 Share Posted June 7, 2009 Is it an adjustable sight on the 9mm slide? I have seen some firing pin stops that protrude up under the sight and if they are cranked down to much make contact with the stop. This could bind things up a bit.
