Questions & Answers
Will this work on a G43X with a threaded barrel Expert Answer

The Killer Innovations Velocity Glock Compensator is not intended for use with the Glock 43 or 43X. It will likely cause functionality issues and will be wider than the slide of the 43. I would recommend using the Tyrant Designs T-Comp Glock 43/43x/48 Compensator, or the TRYBE Defense Universal Single Port 9mm Compensator. Both can be found linked below:

What's the difference between the gen 3 and gen 4 versions? Can I use the gen 4 comp with a gen 3 g19 or vice versa? Expert Answer

The Killer Innovations Velocity Glock Compensators are generation specific due to differences in the recoil system. If you have a Gen 3 you must use the Gen 3 comp etc.

Product Info for Killer Innovations Velocity Glock Compensator

Killer Innovations Velocity Glock Compensator is braking all the rules! This compensator significantly reduces recoil and muzzle climb and attaches in an innovative new way that is completely different than any other compensator on the market. This revolutionary attachment system has a few advantages over the traditional methods.image

First: It can be installed and removed without using tools when using our Velocity Mod 2 barrel. Cleaning your Glock just got a whole lot easier! When used with other brand barrels, tools will be required to add or remove the comp, but accuracy will be maintained.

Second: The compensator pushes all the way back to the thread shoulder when installed. This provides a superior bore alignment to other comps that are timed short of the shoulder, then set screwed or clamped to the threads. This bore alignment accuracy ensures the bullet is passing directly down the center of the comp with equal air gap around the bullet. This equal air gap eliminates the air pushing to one side and wobbling your bullet. Accuracy down range is the ultimate goal!

Every professional shooter we let shoot this comp during testing said this was the flattest shooting comp they had ever shot. We agree! We adjusted the ports and tuned this comp for months before we were satisfied that we had made it shoot as flat as possible and still reliably cycle the slide with a 13lb spring.

If you want a compensator that is extremely accurate and installs easier than any other comp on the market, look no further, weve got you covered!

As always, made 100% in the USA.
