The Jarvis Compensator for the Walther PPQ 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 PPQ 4″ model slide and works with both Jarvis and Walther factory threaded barrels. Assembly and disassembly is simple and quick. To install, simply screw the compensator on and tighten the single set screw located at the bottom of the comp with the hex key wrench provided, no other tools required. Included with the compensator are 2 set screws, threadlocker, hex key wrench, and installation instructions.
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.
