So my basic question is can a mag extension cause a trigger not to reset?I recently got +10 mag extensions from Taylor Freelance for my M&P CORE pistol. It's tricked out to an open pistol. It's just a fun gun. The pistol has the Apex trigger kit in it. It's worked flawlessly up until today.Today was the day to test these TF +10s.Everything fed great. Except I had 5 or 6 rounds that didn't fire because the trigger didn't reset. The gun appeared to be in battery, but pulling the trigger did nothing. No click, no nothing. I'd rack that round out and it'd fire just fine. None of the rounds appear out of spec. It's the usual ammo I use. 124gr S&B 9mm.Is this a magazine issue? or something unrelated and cooincidental?Any ideas?
