TriggerTech Ace Glock

Trigger Review

I am always looking for the next, best trigger. Handguns, rifles, I always want something better. Sometimes you come across one that is just great. That is where the TriggerTech Ace trigger for Glocks comes in.

The TriggerTech Ace Glock trigger is strictly a competition trigger. It is definitely not a carry trigger. The pull weight is adjustable from 2.5 - 6.0 pounds but it does not include a tab safety on the trigger itself. Which is why I say it's a competition only trigger. However, TriggerTech does use a different style of safety in the trigger to make it safe. It also retains all the other factory Glock safeties. I dropped it on the rear of the gun, empty of course, and it locked the trigger from moving, but did not fire. Granted, that was from about 2 feet onto carpet. I had to rack the slide to get it back to working order. I also hit the back of the slide on the carpeted floor, like a hammer, the trigger still pulled fine and bumped a pencil out of it when fired. That was with the pull weight set at 2.5 pounds. I have not had any problems with this sample. But, to mention it again, it is a competition trigger, not a carry trigger.

Let’s get into the Ace trigger itself. TriggerTech sent the Pro curved version. So the trigger is slightly curved with the face being flat. TriggerTech also has Flat and Traditional curved trigger faces if that is what you like. I like the feel of the Pro curved trigger, especially since it is not super curved. I would say it falls somewhere between a flat and a standard Glock curved trigger. Since the Ace is a competition trigger, TriggerTech got rid of the flipper safety on the trigger. They moved this type of feature to the top of the trigger, so no flipper is needed.

TriggerTech’s Ace trigger drops in similar to any Glock style trigger. Amazingly, it can be used in Gen 1-5 Glock pistols and clones. The difference lies in the backplate that has a disconnect function built into it. This backplate has a flat protruding out from it. It installs just like any other backplate, so no worries there. The lever and sear module install like any other Glock trigger. If you do not think you are capable of the installation yourself, please take it to a gunsmith. Now that that is installed, you can safety check it and head out to the range.

What makes the Ace trigger so interesting is the fact that it can be adjusted for trigger pull weight. Depending on what parts are installed, it can be adjusted from 2.5 pounds up to 6 pounds. 3 different springs come with the Ace trigger kit. Depending on what springs are installed, determines the range at which the trigger can be adjusted. If you use a stock plunger spring and the heavy take up spring that comes installed in the Ace trigger, you get a trigger pull range of 4.5 - 6.0 pounds. By changing the plunger spring to the supplied lighter one and keeping the heavy take up spring, you get a trigger pull range of 3.0 - 4.5 pounds. Now if you replace the take up spring to the lighter one, while still keeping the light plunger spring, you get a trigger pull range between 2.5 - 4.0 pounds. Lastly, if you now change the plunger spring back to the stock one, while keeping the light take up spring, you get a range of 3.5 - 5.0 pounds. Since this Ace trigger uses TriggerTech’s CLKR technology, it lets you adjust anywhere in the ranges listed above. Just take the slide off, insert the allen wrench into the sear module and turn it the desired direction. There is a “+” marked on it so you know which way to increase the pull weight. Adjustments are pretty fine, as you can get about 40 or so clicks out of the CLKR adjustment. I was able to adjust the pull weight from 2.5 to 4.5 pounds with just the CLKR adjuster. I also am using the “Light” springs.

Besides being able to adjust for pull weights, the Ace trigger also shortens the physical trigger pull distance. A stock Glock trigger moves a little over a ½ inch to fire a round. The TriggerTech Ace moves 0.200 of an inch. That’s a 60% reduction in total trigger travel. It gets better. The Ace’s pre travel is about 0.100 inches of that. Then the Ace trigger hits the wall that has around a 0.050 inch break. The rest is over travel. It is the best trigger pull I have felt on a Glock. I have only one complaint with the Ace trigger, the reset is a little wimpy. So it is not very forceful or tactile. It doesn’t cause any problems, but I think it is a TriggerTech thing, because their AR triggers also have the same reset.

Since I don’t have any actual Glock pistols, I installed the Ace trigger in a Polymer 80. The installation was easy for me. I tried it as it came supplied at first, using the factory plunger spring. Of course it worked, but I wanted to see how light I could get it using the supplied parts. So I installed the light springs and it made a world of difference. When turned all the way down, I was able to get about a 2.4 pound trigger pull. I adjusted it, with the CLKR, to 2.5 pounds. The first time I pulled the trigger, I had to bust out my 1911 to see which was lighter. The Ace had the 1911 beat in pull weight by ¾ of a pound. The 1911 had a better trigger pull feel. Just remember these are two different styles of triggers, so they will be different. This Ace trigger shoots phenomenally. The pull has no gritty feel like some Glock triggers, just a little take up and then a bang. If you can manage recoil, you can get some really fast doubles and triples out of this trigger.

So far, the TriggerTech Ace trigger is the best feeling trigger, for Glocks, that I have seen. It lets you adjust it easily, as well as on the fly. The feel is just great. I just can’t get over how smooth and short the trigger is. If you are looking for one of the best competition Glock trigger one can get, you will definitely want to take a look at the Ace trigger from TriggerTech.

Feels great!

As far as competitive shooting or range training, this trigger keeps my splits about the same as my Staccato. Although it does not feel like a 2011 or custom Double Stack 1911 trigger, it's definitely much better (feeling wise) than any of the other Aftermarket Glock Triggers I've used. I didn't change any springs but I turned the internal dial 5 notches from the lowest setting. I am about 2.75 - 3.0 lbs according to my trigger gauge. Will I carry it in my EDC or Duty style weapon even with a higher setting on the internal dial? Not yet, not until I at least have a few thousand rounds on it. The lack of a bladed safety does have me at a slight pause and I know to some it's trivial. I'd like to see TriggerTech give us a trigger option that includes a small trigger blade safety like what Agency Arms does with their triggers. Just a little extra piece of visual/tactile assurance.
