Frequently Asked Questions

What are the key testing criteria for Glock compensators?

Key criteria include reliable cycling with standard range ammunition and compatibility with OEM guide rod springs (around 18 lbs for Glock 19/17). The compensator must also reliably lock the slide open on the last round.

What unique feature does the Agency Arms 417 compensator offer?

The Agency Arms 417 compensator has a unique design that allows a front sight to be mounted directly onto the compensator itself, aiding in shot tracking during slide cycling.

How does the Agency Arms 417 compensator perform with different recoil springs?

It performs reliably with standard 18lb OEM springs. Using a lighter 13lb spring did not significantly improve muzzle flatness and risked failures to return to battery.

What is the main compatibility issue with the Agency Arms 417 compensator?

The primary drawback is its proprietary nature; it's specific to either Glock Gen 3 or Gen 4. Swapping between generations requires a workaround using a Gen 3 guide rod and a reducing ring.
