Agency Arms 417 Compensator Glock 43
Agency Arms 417C Compensator, Glock 43
So your G43 kicks more than you’d like for a carry gun you actually train hard with. This compensator fixes that. The Agency Arms 417C, built specifically for the Glock 43 platform. Dual chamber design. Thread-on install, no gunsmithing required.
This is not a universal thread-on muzzle device. Also, this is not a bulky comp that ruins your G43’s slim profile. First, this comp is purpose-built for Slimline Glock dimensions. Next, it uses a dual chamber venting system to fight muzzle rise. Finally, it keeps a front sight hole, so you don’t lose your sighting setup in the process.
Will this Agency Arms 417 Compensator Glock 43 fit my Glock 43?
Yes, if you have a properly threaded G43, G43X, or G48 barrel. So this comp is built for the Slimline Glock family specifically. However, it is not compatible with AlphaWolf, SilencerCo, Fortis MFG, Faxon Firearms, or factory OEM threaded barrels. Therefore, confirm your barrel brand before ordering, since fitment depends on precise barrel protrusion specs, not just thread pitch.
How does the dual chamber design actually reduce muzzle rise?
Agency Arms 417 Compensator Glock 43 Gas redirection, both up and to the side. So the 417C uses 2 vertical ports and 2 side venting ports. Also, that combination redirects propellant gas away from a straight backward push, which is what drives muzzle flip. Therefore, you get flatter recoil and faster follow-up shots, especially noticeable during rapid strings of fire.
Do I need to modify my slide or barrel to install this?
No modifications needed, but precise barrel protrusion matters. So installation is a simple thread-on process using the provided set screws, hex key, and a vial of Rocksett for a secure mount. However, overall barrel protrusion should measure 0.637 inches, plus or minus 0.005 inches, for correct fitment and function. Therefore, measure your barrel before ordering if you’re not running an Agency Arms threaded barrel already matched to this spec.
Does this comp work with my factory recoil spring?
Agency Arms 417 Compensator Glock 43 Yes. So the 417C is designed to use your OEM recoil spring assembly. Also, no special spring kit is required out of the box. However, some shooters find tuning the recoil system helps reliability, especially with lighter target loads. Therefore, expect best performance with standard or heavier-charged factory ammunition rather than the lightest available loads.
Who is this compensator best for?
This Agency Arms 417 Compensator Glock 43 fits G43 owners who want flatter recoil without bulking up their carry or range gun. So if you’re already running a threaded Glock barrel and want to tame muzzle rise, this comp delivers that. Also good for competitive shooters and anyone building a custom Agency Arms G43 setup who wants matched components.
