I noticed that the Apex trigger seemed to offer a longer length-of-pull. Having a few different ones on hand, I tried to line up a few on a sight in target to show how they compare. Connector is the same for all photos. Frame is a Polymer80, but in comparing the triggers to each other, and nothing else, this shouldn't matter.
OEM plastic Glock trigger:
Vickers/TangoDown plastic trigger:
Apex trigger:
I have large hands, and I like the additional length-of-pull that the Apex offers at least for the 9mm/.40 frames, and it reduces the trigger pull by a few ounces. The trigger safety dingus will go flush or below flush with the face of the trigger when depressed, and is quite comfortable.
The Vickers safety dingus sticks out when depressed, and the toe is a bit sharp, which can be irritating, and could possibly cause a blister during a pistol class or a high-round-count shooting session. The Vickers trigger is about half the price of the Apex ($35 vs. $75), but I still prefer the Apex.
