P320 shoots flatter than the earth - Herrington Arms SIG Sauer P320 HC320XL Pistol Compensator

This compensator not only looks great it functions perfectly. I put it on my P320 and put 200 rounds through it without a single problem. I left the stock recoil spring in and I was using 115 grain 9mm, it handled it perfectly. I highly recommend this product. It is easy to install, and the price was excellent. It shipped quickly, and I could not say enough good things about ordering from optics planet.
