The Herrington Arms HC320 Compensator is designed to work flawlessly with Sig Sauer P320 series, it does an amazing job at reducing vertical climb of muzzle as well as reducing the horizontal recoil arc, it is made of high-quality 6061 aluminum and coated with Black Cerakote finish to compliment your Sig P320 configuration.
Works great with stock springs so no need to change anything, fits on 1/2-28 threaded barrel X-Compact, Compact, X-Carry and full-size P320’s.
I bought this for a SIG P320 and paired with dpm system and it shoots extremely flat. Love it!
