Glock Trigger Upgrades by Zev Technologies

One of the most routine of upgrades for any gun is a drop-in trigger. Since Glock pistols are so common it goes without saying that aftermarket upgrades would be available. Zev Technologies makes a great Fulcrum drop-in trigger for Glocks.  My recent trigger upgrades were in my Glock 19, 23 and 21. Each one was a little different because of caliber and since the fact that the 19 is a Gen4; the 23 is a Gen3; and the 21 is a short frame (SF).

I wanted to change out my triggers because the OEM is not completely flat on the front where the trigger safety resides, even when the trigger safety is pressed to the rear, just a enough of a nub protrudes forward of the the trigger. Also, some Gen 3 triggers have more vertical grooves that aid in finger grip and suffice to say more conducive to pulling the trigger with the first joint rather than your first digit's pad. The Zev trigger is slightly wider than OEM and with a true flat face on the trigger with a trigger safety that sits flush with the rest of the trigger when depressed rearward.


They are pretty simple to install if you are at least accustomed to the Glocks under-the-covers components. As a certifed armorer for Glock pistols, this was a routine dis-assembly to remove the old trigger with trigger bar and trigger housing that houses the ejector. The directions that accompany the replacement parts are easy to follow which means the average shooter should be able to do it themselves. At first I wasn't sure about these drop-in triggers for Glock because I had never done one. In the past, the only trigger upgrades I did were on my ARs and those were Timney and CMC triggers. The Zev triggers were just as easy as the ARs.

I came across the Zev Technologies trigger on MilSpecDepot but eventually ordered the drop-in kits from Brownells. However, Brownells doesn't stock all the color variations as does MilSpecDepot.

The other standard upgrades on my Glocks are extended mag release, enhanced slide stop, and TFO front and rear sights by TruGlo.
