The Herrington Arms HC365 Compensator is designed to work with Sig Sauer P-365 series. The HC365 will work with the stock springs provided your gun has gone through our recommended break in period of 500 rounds factory new ammunition is used with the threaded barrel you intend to use with the firearm before installing a compensator. This comp is designed to cut down on vertical and horizontal recoil of your gun and help mitigate the felt recoil of a smaller 9mm platform like the P365. When testing this compensator, we have data showing 29% muzzle flip reduction depending on what 9mm load and 365 model is used.

INSTALLATION INSTRUCTIONS
Make sure all threads are clean of grease, carbon, and loctite. Wipe the threads down till they're clean. If the threads are not cleaned, the loctite will not set properly.
Only use loctite 243 on the barrel AND set screw threads. Some versions of the blue Loctite are not very strong and will not hold up. Feel free to use a generous amount.
Torque the set screws to no more than 18in/lbs for 8-32 set screws and no more than 11in/lbs for 6-32 set screws.
Allow the loctite to set for 24-48 hours before using.
Please be sure that the compensator is not touching the slide, frame, or guide rod as that can cause cycling issues.
