Requires a THREADED BARREL in 1/2-28. Most of these pistols do not ship with one — check your barrel before buying. Product name (read 2026-09-21): "Springfield Hellcat & Pro True-Lock Compensator". The compatibility box prints only "Springfield Hellcat", and the page sells a Hellcat 3.1" spring kit and a Hellcat Pro 3.7" spring kit with the comp. Pro is a named host in the product name, so the Pro OSP card is included. Pro Comp and RDP ship with an integral compensator and are not named. A spring kit is recommended for light ammo and is not required.
