Oh yeah, way better than the previous one! - Herrington Arms Gen 5 Glock 19/17/26/34/45 HC95 Pistol Compensator

Just order it. It works with stock springs. All you need is a threaded barrel.

I had previously ordered a Strike Industries Quad V Compensator. It was a nightmare. The quality wasn't there. It didn't cycle properly without tuning a spring. I don't remember which spring worked, but even after I tuned it, one out of twenty rounds would stovepipe. I was going to cut a coil or two off, but I noticed the rounds were all over the place. A closer inspection of the target paper showed the problem. It was causing the projectile to tumble. I returned it and ordered the HC95 after an AI search on which compensators were the best for a Glock 19 G5. It was between this one and one other that isn't sold by optix planet.
I couldn't be happier. I shot 100 rounds through it this morning and didn't have a single issue. I used the stock recoil spring and all! The screws did come loose, so I put some blue locktite on them. Importantly, the design of the flares on it prevents the comp from backing off, so that's not something to worry about. Also, I didn't have to adjust my sight. The aim stayed true �. I'm keeping this one! Screw Strike Industries. I'll never buy one of their products again. If you made it this far, thanks for reading my review. I will be posting a video on YouTube of my range time this morning. I'll update the review page with a link.
I almost forgot; If you have a light attachment this compensator redirects the gas so your light stays clean!
