Description
Glock triggers are famous for a lot of things, but a crisp feel usually isn't one of them straight from the factory. This CMC Triggers Glock Flat Trigger Kit swaps out the mushy stock unit on your .40 caliber Gen 4 pistol and replaces it with something that feels a whole lot more deliberate. It's built around CMC's patented Signature Flat trigger design, which trades the standard curved bow for a flat face so your finger settles into the same position on every press. That flat geometry gives you a bit more leverage and encourages a straight rearward pull, which usually translates to tighter, more consistent groups once you get used to it.
What Sets the CMC Signature Flat Trigger Apart
CMC downsized the overall geometry specifically to fit the Glock frame, so this isn't a repurposed AR part crammed into a pistol. You get a clean take-up, an ultra-short reset, and a positive reset feel that lets you get right back on target for fast follow-up shots. The contact surfaces are made from 8620 alloy steel and S7 tool steel, both of which hold up well to serious round counts. It maintains the safety features you'd expect from a Glock trigger while improving the feel across the board.
Fitment for Your .40 Cal Gen 4 Glock
This kit (part number 71801) is made for .40 S&W Gen 4 pistols, which covers models like the G22, G23, G27, and G35. It will not work on Gen 5 Glocks, so double-check your generation before ordering. CMC also makes separate versions for 9mm and .45 ACP/10mm, so match the caliber to your pistol.
Installing the CMC Flat Trigger Kit
This is a self-contained, one-piece assembly, which is a big part of why folks like it. You're dropping in the fire control group rather than fiddling with a pile of loose springs and pins. Most people with basic hand tools and a punch can knock it out at the bench in a few minutes. If you're the type who enjoys a little tinkering, a light touch on fitment at the rear of the trigger can smooth things out even further.

Frequently Asked Questions
Which Glocks does the CMC 71801 flat trigger kit fit?
This kit is built for .40 S&W Gen 4 Glock pistols, which covers models like the G22, G23, G27, and G35. It will not fit Gen 5 Glocks, so confirm your pistol's generation before installing. CMC offers separate kits for other calibers and generations if this one doesn't match your setup.
Does the CMC Glock flat trigger reduce pull weight?
CMC doesn't advertise a specific pull weight reduction, and many owners report the weight feels close to OEM. The real gains come from the flat-faced geometry, cleaner take-up, and short positive reset rather than a dramatically lighter pull. The flat face gives you more leverage, so the press often feels smoother even when the weight is similar.
Is the CMC flat trigger kit hard to install?
Not particularly. It's a self-contained one-piece assembly, so you're dropping in the fire control group instead of wrestling with individual springs and pins. Most people can complete the swap at the bench with a punch and basic hand tools, though a little fitment at the rear of the trigger can help it run its smoothest.
What makes the flat trigger better than the stock curved Glock trigger?
The flat face lets your finger rest in the same spot every time, which builds a consistent index point and encourages a straight rearward pull. That geometry gives you slightly more leverage and often translates to tighter groups once you adjust to the feel. You also get a cleaner take-up and shorter reset compared to the factory unit.
