I didn't measure another guns slide stop lever, but I did have a strange issue where the trigger felt extremely heavy and had a distinct hitch in pull and reset using the OEM "minus" connector when installed in my 34.5. The issue seemed to lie somewhere in the trigger bar-connector interface. Swapping the original OEM minus for another OEM minus I had on hand made that issue completely go away. This 34.5 has always had an odd hitch in the pull with the original OEM parts, and I really have not shot it enough to smooth things out. Very strange, and makes me somewhat distrust the Apex without some further vetting, but it may be the original OEM minus that is the culprit here. I did notice that the trigger shoe fit more "snug" in the slide stop lever of the 34.5 too, though it still moved freely. I should have measured that, but the hitch in the trigger distracted me.
I put about 250 rounds through my 19.5 with the Apex installed before I did all this, with zero issues. I've reinstalled my OEM trigger in the 19.5, and moved the Apex to the 34.5 for farther consideration and testing. I have another 19.5 and a 26.5 I could also try it in, and I may get around to that at some point.
Sorry for the thread drift. Back on topic... it does seem that Glock is changing or updating the Performance Trigger. If you try to click links on their dedicated webpage for the trigger, there are some dead links.
