Glock frame tolerances are not consistent. - Apex Tactical Specialties Glock Gen 5 Action Enhancement Kit

I bought this trigger because I have the same one in another Glock 19X, and the reset is almost as good as Canik's. This Apex, however, is not the same. The reset is twice as long and comparable to the stock Glock trigger. I returned it thinking it was the trigger at fault. After contacting Apex, I was told that the Glock frames are all over the place and inconsistent in tolerances frame-wise. I also heard this from YouTuber Johnny Glock when he did a segment on triggers. I gave the trigger five stars because of the one I have. The one I returned is probably a five-star, just not in my frame. Hope this helps someone.
