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.

Made the trigger too light and feel like a sponge. Created fail to fire malfunctions from light primer strikes. The only part I kept was the safety plunger spring.

Worthless

The ZEV Competition Spring Kit includes the 2 lb. striker spring, reduced power firing pin safety spring, and an extra power trigger spring. I ran into numerous failures to feed, light primer strikes, and failures to reset with my 3rd gen Glock 17. While my trigger pull weight was reduced to 2.5 lb with a Scherer 3.5 lb connector, I replaced all of the springs with stock and used a Wolff 4 lb reduced power striker spring (due to my 15 lb. ISMI recoil spring) and the trigger pull weight was 3 lb, a whopping 0.5 lb heavier. I recommend avoiding the ZEV spring kit.

Unsafe with the Glocks I tried this on.

The trigger spring is to long and the safety reset spring did not work. I would not even load a Glock with this set up in it. I tired it on two different Glocks and it does make the trigger more crisp it's useless when it disables the safety. I went back to the Lone Wolf 3.5 lb. trigger bar and 6 lb. spring, that's perfect for the average shooter. If you don't spend a good bit of time shooting and know your firearm well you may not notice the trigger safety reset. I tried this out for my son whom is military and my nephew who is a sniper on a SWAT team.

O.K. but not great

First the spring kit did not come with the three springs as advertised as the striker spring was not included. Second the striker safety spring did not fit as it was too small for my particular pistol. Third the trigger spring felt mushy and required a conscious effort during the trigger press to release the striker. Maybe the second and third reasons are related, I'm not sure. The trigger spring did lighten the pull over the stock spring and had a crisp reset but I just didn't like the break of the trigger.

Failed Part

The trigger spring broke after 1,500 rounds. I put the original spring back in and it now has about 5,000 rounds on it. This product is inferior to the OEM part.

Outshoot All the Guys at the Range

If you want to out-shoot all the guys at the range buy one of these spring kits for each guy. For every 15 rounds, I get 5 misfires! I am an Armorer. One of my friends kept asking about this kit so I bought one to try in my G17. Very little, if any improvement in trigger pull and 30+% misfires. Spend your money on practice ammo.

Wolff is a better choice

Striker spring is too light. I purchased four kits and three of them failed to ignite primers within the first 150 rounds after installation. Wolff spring kits have never given the same trouble. Back to Wolff...
