TRIGGER UPGRADE COMPONENTS FOR GLOCK® Reviews & Ratings

TRIGGER UPGRADE COMPONENTS FOR GLOCK®

Drop-in parts give your Glock® a smooth, crisp, light pull that helps promote consistent, match-grade accuracy. Change specific components to improve a particular aspect of the trigger pull, or do a complete upgrade. Fits all Glock® pistols. Precisely calibrated spring weights deliver consistent force through the entire compression/release cycle to give you a light, refined trigger without sacrificing the reliability of your pistol’s Safe Action system. High-stress, aerospace-grade stainless steel spring wire is heat- and cryo-treated for 99.99% consistent energy output, so trigger pull feels the same every time.

FEATURES

Trigger Spring has nearly 30% more power than factory spring, yet actually reduces pull by as much as 1 lb. for improved control. Also produces faster trigger reset for quicker follow-up shots.
Reduced Power Safety Spring reduces friction caused by the firing pin safety, further smoothing the pull. Striker Spring is designed for improved consistency and durability over factory spring.
Light Model reduces pull by at least 1 lb. to a consistent 2 to 2½ lb., while preserving reliable primer ignition.

SPECS:
Spring stainless steel wire.
Fits all Glock® pistols.

Ok, but probbaly not needed

Installed this along with the ZEV 3.5 connector. Had problems with the trigger reset with the trigger spring. The hooks don't fit right and cause binding and the trigger to not reset all of the way. Put the stock trigger spring in and trigger pull is now great. Maybe some day I'm mess with it a bit, but not now. IMO this spring kit did little.

Careful! This requires some knowledge..

So I bought this kit with a 3.5lb connector to put into my Gen 4 19. The kit was easy to install if you know what you are doing, but the firing pin safety spring is black and was a pain to install and ended up losing it; used the factory one instead. The real problem for me is the firing pin spring. This caused some failures when functioned tested with the 3.5lb connector. The failure would lead to whatever magazine slam firing the entire mag when loaded. Also, another failure I found is when you depress the trigger, but then let off, the trigger safety does not reengage. I had to manually pull the trigger body out to get the click. So, because the firearm is for CCW use, I returned to stock. I then used the 3.5lb connector to reduce the trigger pull and I am happy with that. I didn't think Zev would make crap, so I experimented and installed this kit into my Gen 3, 21C and it worked perfectly. Definitely wouldn't carry for duty use, but it's great to shoot now. Very light trigger pull and pairs are very close. All in all, it worked out; not for the intended purpose, but it worked.

Maybe, maybe not?

The trigger pull is great after installing this and a connector, but I have one problem. To describe it best, it's like the trigger safety gets "hung" on the Glock frame. I installed two on different Glocks and they both did it. I haven't gotten into a cure yet, but it will take one. I wouldn't recommend to someone who couldn't tweak this.
