Angency 417 Single Port by james, Verified Owner, March 20, 2026
Slapped this on my g17 gen4, replacing my jet upgrade from last year. Solid product and same performance as its 400 dollar competition. Its a better bang for your buck.

Product Info for Agency Arms 417 Glock 17/19/34 Gen4 Single Port Compensator

The 417 Gen 4 Single Port compensator is a thread on compensator designed for select Glock Gen 4 models. It features a 1 chamber design ( 1 vertical venting port). It is designed to work with threaded barrels with a 1/2x28 thread pitch (Overall barrel protrusion should be 0.695" +/- 0.005" for optimal fitment). It features a front sight hole allowing you to transfer your existing front sight from your slide to the compensator. It is compatible with the G17, G19 and G34. (Not compatible with conversion barrels). Please note compensator may require tuning of the recoil system. It is designed to work with most factory loaded ammunition but will yield the best results with a heavier charged ammunition.image
