Lior Posted December 23, 2015 Share Posted December 23, 2015 (edited) Hello folks. I have two M&P pros with flat triggers and the forward set sear installed. In the second gun, I had to bend the connector loop up a bit for it to reach the sear. Here's a video of the gun not resetting consistently. When the slide is forced slightly to the right during racking, the striker does not get cocked by the sear (i.e. the trigger bar loop is not letting the sear catch the striker despite the trigger being held back). https://www.youtube.com/watch?v=RCdF8gW-nY8 Any tips in remedying this situation would be appreciated.

CHA-LEE Posted December 23, 2015 Share Posted December 23, 2015 Take the slide off and test the loop to sear reset process. If the trigger pretravel is set too shallow the loop will not be able to get in front of the sear to reset properly. You may need to pinch down the loop a little to create the proper amount of pretravel before the loop touches the sear. Link to comment Share on other sites More sharing options...
Lior Posted December 24, 2015 Author Share Posted December 24, 2015 (edited) Follow up: after swapping slides between two M&P pros, one of which I have been shooting for a while and functioned reliably, I concluded that the striker's tab was missing the sear during cycling, by being too high or constrained in the striker channel. After detail stripping the offending striker assembly and cleaning everything, the gun functions well, even if I pull upwards/ rightwards on the slide during cycling to reset. One suspect was the geometry of the coils of the striker spring. Edited December 24, 2015 by Lior Link to comment Share on other sites More sharing options...
mpom Posted December 24, 2015 Share Posted December 24, 2015 With loaded mags the slide is pushed up, reducing striker tab and sear engagement. If i was in your situation, i would replace the offending striker assembly. Probably an expensive hassle in Israel. Glad you got it sorted out. Yofi!
