Nice and easy - Apex Tactical Specialties Action Trigger Assembly Enhancement Kit

I bought this trigger to replace the one on my Massachusetts compliant 10.5 pull S&W Shield M&P 9mm. It is "easy ' to install if you have the right size punches to remove the pins holding your gun together. There are also YouTube videos showing exactly what to do. These are a MUST because it is a little tricky. It took me a couple of hours because I was careful and double checked every move. What a difference the trigger made ! I do have a Armalaser and I was very happy at the range. All shots from my 8 round mag were either bullseyes or no further than an inch from it at 8 yards .The trigger was so smooth there was little movement of the laser off the bullseye when squeezing off a round. I'm very happy.
