Your Questions Answered
What ammunition does it work best with?
In our testing, it performs reliably with standard-pressure 115gr and 124gr FMJ rounds. We had one hiccup with a specific brand of 147gr subsonic ammunition; for heavy subsonics, ensure your pistol has sufficient slide velocity.
Will this fit my Glock 19 with a threaded barrel?
Yes, if your barrel has a standard 1/2x28 thread pitch. It is compatible with most common 9mm platforms including Glock, SIG, CZ, and others with matching threads. Always verify thread compatibility before purchase.
Is this a suppressor or a compensator?
This is a compensator, not a suppressor. It is designed to manage recoil and muzzle rise, not to reduce sound. No tax stamp or paperwork is required for purchase.
