The Jarvis Compensator for the Walther P99 9MM reduces muzzle rise enabling the shooter to get back on target quicker after each shot. With a single, large port located at the top of the comp, the compensator redirects a large volume of gas upward reducing the muzzle rise and perceived recoil. Designed for use with standard ammunition, the compensator performed flawlessly in testing with all factory ammunition from 115 gr to 147 gr subsonic. With a sleek design, the compensator follows the profile of the P99 9MM slide. Assembly and disassembly is simple and quick.
NOTE: Please read additional info at the bottom of the page regarding the reference flat for the set screw that we put on the bottom of the barrel threads.
