Can I use any threaded barrel?

Manufacturer Answer
A
Answered by Killer Innovations, Manufacturer from WA, United States, on August 20, 2025

Killer Innovations compensators are designed to pair with our Velocity Defense barrels to take advantage of the tool less removal feature. However, if you want to install them on a different barrel, 1- they need to be threaded 1/2-28, right hand threads, 2- have the same thread shoulder as OEM.

Manufacturer Answer

We guarantee fitment with OEM applications as well as our Velocity line of parts. This has not been tested on the PSA Sabre Dagger and therefore cannot be recommended.

Q
Nestor, member, from CA, United States, asked on December 09, 2023

what recommended ammo grain / load? 115 gr won't cycle even with 13lb spring.

Manufacturer Answer
A
Answered by Killer Innovations, Manufacturer from WA, United States, on August 06, 2025

We have a helpful video available that goes over some common issues when running a compensator https://www.youtube.com/watch?v=1ETVVw81AqI
A compensator is designed to take the gases released from firing ammunition and redirect them in a way that is more advantageous to the shooter – resulting in flatter shooting and faster follow up. However, the compensator robs momentum from the slide action during this procedure. Always be sure to run high quality ammunition to ensure enough cycling power on your firearm with compensation.
We recommend using American Eagle 115 grain ball, or Herters Ammunition.
Ensure your barrel and slide are fully broken in before attempting to run a compensator.

will, member, from WI, United States, asked on January 13, 2023

will this work with a glock 26 gen 4 with a killer innovation threaded fluted barrel?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on April 21, 2023

The Killer Innovations Velocity Glock 17/19 Gen 3 Barrel Compensator would not work well on a Glock 26 Gen 4. This compensator is specifically designed for the slide and frame contours of Gen 3 model Glocks. It would also cause reliability issues on a Glock 26.

Q
William, member, from TN, United States, asked on February 26, 2021

Can I use this compensator with other 9mm guns?

Expert Answer
A
Answered by Kurt Colbourne, Gear Expert, from IL, United States, on July 23, 2021

This should be capable of function with other pistols. They will still need to be Browning action pistols or fixed barrel pistols though. This compensator was designed to match the slide's silhouette, so expect some edges to be able to catch when used in a holster.
