Gigliotti trigger is what this platform needed
Finally got the range. I'm very impressed with the update and it's certainly what I needed to make the TP9 worth keeping. I don't have a gauge but it feels very similar to a stock Glock trigger (aprx 4.5lbs) and will hopefully break in and improve like a Glock.
Installation was pretty simple with some minor issues I spoke about in my last post. Put 300 rounds of 124gr Federal through it today. (Would've done more but it was hot and sticky and I had a BBQ to run) Off the bench, slow fire, 25yds, it held pretty good with about a 4" spread. Much better than the 10" spread I was getting with the stock trigger.
On the trigger itself. I've got a few gripes. I'm not a fan of the way the new sear group is held in place with the two screws coming in from both sides of the frame and attaching to the trigger grip itself. In my older model (circa 2013) the screws needed to be left about 2 turns out, or they would pull the trigger group up off the bottom of the plastic frame where it would catch on the bolt and prevent it feel cycling. One other weird issue, I can't seem to fix despite several attempts making adjustments. If I pull the trigger past the break all the way into the frame, the trigger will not reset under fire or during dry fire. There's a good bit of "squish/takeup" in the pull up to the wall, but the break is clean. The reset is slightly longer than I would like, but a vast improvement over the factory, so no real issue there and I don't think either issue is really fixable given the design of the trigger. While the metal of the trigger shoe and trigger bar isn't "raw" it has a very minimal coating that I don't find very appropriate given the cost, and plan to keep well oiled to prevent wear and rust. My $200 Geissele triggers have a much nicer finish.
Overall, I'm extremely happy with the improved performance, and very excited to actually enjoy shooting this gun for a change. Since the trigger was only manufactured in the last few years, I'm not really surprised by the issues that cropped up for me in my older platform. None of which are deal breakers.
I just hope that Gigliotti makes a few "quality of life" improvements in the future. This trigger was not easy to develop, and I'm sure the cost reflects that, but for that cost, I expected a little better final product.
