My midsize M&P45 likes to FTRB. When it hangs up its maybe 1/8" shy of where it should be. I've read of the extractor tension issues, but I can replicate this with an empty chamber so I don't think that is an issue.
Gun has the DCAEK in it, and i put the slightest of bends on the trigger bar. Note that this issue occured before I bent the trigger bar.
With an empty chamber, I can get it to hang up with the trigger released but with the trigger held to the rear it will not exhibit this behavior. One last data point, when it is hung up with the empty chamber I can pull the trigger to return it to battery. However, when I've noted this while live firing, I get a dead trigger.
My thoughts are that it is tied to the interaction between the trigger bar and the striker block. I think that pulling the trigger (which feels like a "wall", not a normal pull) depresses striker block enough to allow everything to move forward. I'm just not sure how to narrow it down from there.
Any thoughts from the experts? Thanks.
