Glock 43 Compensator 417 Single Port – Black
This is the clean “make it shoot flatter” upgrade for the slim Glock. One top port vents gas up to calm muzzle rise, and the front sight hole lets you move your front sight forward onto the comp for a slick, integrated look.
Fitment
Fits slimline Glock platforms including Glock 43, 43X, and 48 when using a 1/2x28 threaded barrel.
For best fit and function, barrel protrusion should be 0.637 inch ± 0.005 inch past the slide.
Does NOT fit
Does not fit non-threaded barrels.
Does not fit barrels that do not match the protrusion spec above.
Assumption to avoid returns: your feed line says Glock 43, but the manufacturer lists this 417C slimline comp family as compatible with 43, 43X, and 48. What to verify: your exact model and your barrel protrusion measurement before ordering.
Tools needed
Allen wrench for the set screws (included).
Degreaser for barrel threads.
Optional front sight tool if you’re relocating the front sight.
Install notes
Degrease the barrel threads first.
Thread the comp on, align it, then tighten the set screws.
Apply the included Rocksett or thread locker and let it cure before live fire.
Any required warnings/notes
Comps can require recoil tuning depending on ammo and setup, especially on slim guns.
Threaded barrels and compensators are restricted in some places. Know your local rules before ordering.
