So, the Apex trigger. Is it the rolling type of trigger pull (I think you said you liked)? Or is more crisp with short reset, shorter trigger pull and a nice crisp break? The Apex triggers I have on my M&P 2.0 pistols are awesome.
As you well know, striker triggers are so different from a hammer trigger that they take some getting used to. Fortunately for me, I always liked a slightly heavier trigger than most folks, even in a hammer gun, so the transition to the striker was not too bad for me. I found that to be a pleasant surprise, as I was very skeptical when I first got the P-10C.
A CGW striker and a 4 lb Glock striker spring and retainers got the trigger pull down to something I could work with and that is all I had done to my three P-10's prior to trying the Apex disconnector. But the C trigger was pretty good pre-Apex, the S was maybe a little smoother, and the F was still a little sticky, with a heavy wall and then a break. I could shoot it OK, but it took a lot more thought. I think the differences in the three pistols some down to tolerances and perhaps some production line changes on the trigger bars, there have been 5 or 6 variations from CZ on the trigger bars themselves. (I was not aware of that prior to reading the instructions for the Apex parts.)
Changing that ramp angle smooths out the pull, but with more trigger travel so the break happens "later" in the pull but without any spike in the wall. It may be that the trigger bar contact surface is also smoother at the new contact location than at the original and that may be another benefit with my particular F trigger bar. So, with the Apex disconnector, I have a longer trigger pull but at constant pull pressure and a smooth break, rather than a clearly defined wall with a crisp break like I have with the C and S. I'm thinking a lot of people would NOT like my trigger preferences, but I think I have demonstrated that I can release a shot without moving the gun, and that is what matters to me, not speed of a followup shot.
I'm also pretty much able to adapt to some poor triggers, at least for a short period of time. But, if I am going to shoot one or two pistols for weeks on end, I want them to be "right" for me, in order to minimize the mental challenges, LOL.
