Description
The Tyrant CNC I.T.T.S trigger (Improved Tyrant Trigger System) is a drop-in replacement that transforms how your Gen3 or Gen4 Glock performs. Machined from aerospace-grade aluminum and finished in blue with black hardware, this trigger delivers measurable improvements in feel and function without changing pull weight. The main appeal is speed and consistency—the 15% reduction in take-up gets you to the break faster, while the 10% reduction in reset travel means quicker follow-up shots when you need them.
What Makes the I.T.T.S Design Stand Out
This is a hybrid trigger that splits the difference between curved and flat designs. The top half is nearly flat for a direct finger placement, while the bottom has a subtle curve that helps position your trigger finger naturally. It's not a radical change from stock, but the aluminum construction and refined geometry make the whole stroke feel crisper and more predictable than the factory polymer trigger. The 30% power spring is the real workhorse here—it returns the trigger face with aggressive force after each break, enabling those faster resets you'll notice right away at the range.
Installation and Compatibility
This version includes the trigger shoe and trigger bar, so you get everything needed for a complete drop-in installation on Gen3 and Gen4 frames. Installation is straightforward and takes around 30 minutes with basic punch tools. The trigger maintains all factory safety features, including the safety blade that extends slightly beyond the standard Glock trigger and has a more pronounced edge. You'll feel it until you actually press the trigger, then it melts into the pull. Compatible with Glock 17, 17L, 19, 22, 23, 24, 26, 27, 31, 32, 33, 34, 35, 37, 38, and 39.

Frequently Asked Questions
Does the I.T.T.S trigger come with everything I need to install it?
Yes, this version includes both the trigger shoe and trigger bar, so you get a complete drop-in assembly. Installation requires only basic punch tools and takes roughly 30 minutes. The trigger maintains all of Glock's factory safety mechanisms, so you're not sacrificing any safety features.
How does the I.T.T.S trigger compare to a stock Glock trigger?
The main differences are in feel and speed. The I.T.T.S reduces take-up by 15% so you reach the break faster, and the reset travel is 10% shorter for quicker follow-up shots. The aluminum construction with the hybrid flat/curved design feels crisper and more predictable than the factory polymer trigger, and the 30% power spring delivers a noticeably aggressive reset.
Will this trigger work on my Gen5 Glock?
No, this model is designed specifically for Gen3 and Gen4 frames. Tyrant CNC makes a separate I.T.T.S trigger for Gen5 pistols if you need one for that platform.
What's the trigger finger reach like on the I.T.T.S?
The I.T.T.S has a slightly longer reach than stock Glock triggers, which works better for shooters with larger hands. If you have a smaller grip or prefer a shorter trigger reach, this is worth keeping in mind, though most shooters adapt quickly after a few range sessions.
