3.0 HC9C replacement set screws

The order process was easy and the shipping was fast. And I got 2 sets of screws.

I ordered replacement screws for my comp. I received a shipping notice 12 minutes after ordering. That was definitely impressive.

The Compensator arrived quickly and the finish was clean and good looking. Once I got it attached to my G19 with aftermarket threaded barrel, I was amazed at the noticeable difference. The smaller amount of flip made it easier to shoot faster while maintaining accuracy. I did have cycling issuegetting several stovepipes when using the standard RSA. I solved that issue by installing a well worn OEM spring with about 10K rounds on it. Everything worked well after that. I don't have a way of measuring how much that spring was weakened by it's use. I decided to order another RSA with a 15 lb spring hoping that will work better than the OEM 17lb spring, that I originally tried. A possible reason for the spring issue may be that I have added a Red Dot to the slide. Small issues for the improved performance My only quibble is having to attach the Compensator with screws making it complicated to clean. I have other brands that tighten with an O-ring washer and they are easy to remove. I am trying to keep the barrel reasonably clean by using a bore snake and not taking everything apart for a complete thorough cleaning. Compensators are notorious for fouling if not maintained. I have been cleaning my HC9C itself, with Frog Lube Paste after every session. This leaves a very light coating on the Compensators that makes most of the fouling come off with a quick cleaning with a Q-Tip style swab after shooting. So far so good. I was aware of the mounting issue when I ordered so I can't really complain. The tiny HC9C's performance on my Glock makes me give it a solid 5 star rating even with the small issues with maintenance.
