Most Helpful Positive Review Loved this compensator!
Great fitment once I knew what I was doing. Set screws seem pointless but let me tell you. Made my G19 feel like I was putting rounds through a .22. Only compensator I will be buying for my other firearms. Agency Arms makes good stuff!
Most Helpful Negative Review be careful
This compensator didn’t fit my grey ghost v1 slide. It just wasn’t flush. You may need OEM or agency arms slide for proper fit. Just something to consider before purchasing. I’m sure it’s a great comp if it fits

by Felix Chaco, Verified Owner from GU, United States Written on July 16, 2024
This is an excellent comp with a decent price point. My G19X coupled with a 15lb spring and rod set-up shoots flat and smooth with no malfunctions after 100 rounds of straight shooting.
Pros:
  • Looks like a factory part
  • Easy to intall
Cons:
  • None

Great Comp, but do your research.

by Incognitjo, from CO, United States Written on February 19, 2022
Great product from Agency Arms. You do need to be certain that your barrel is going to function with it though. I've got a GGP threaded barrel and the threads do not close the gap from the front sight tool access hole on the double ported comp when properly timed to my slide. So it becomes a 5 port comp,one port down, unintentionally . I'm sure some barrels with longer threaded areas would work fine. I'm going to tap the access hole walls and get a set screw to plug it up.
Would recommend: Yes

Agency Arms 417 Comp

by Smiffery, from TX, United States Written on August 29, 2021
Clearly a quality piece of gear. Installation was simple and easy. Agency has a great install video on their YouTube channel. Comp is obviously made to pair with the Agency Arms barrel. It will fit other aftermarket barrels but NOT all. It did not work with my blacklist barrel. It’s effective and looks great. I think it’s well worth the price. Optics Planet shipped it quickly and with no hassle.
Would recommend: Yes
