Drops in, works well - Springfield Armory Hellcat 9mm Luger Threaded Barrel w/Self-Indexing Compensator

The barrel is very easy to install. It drops in where the stock barrel sits and fits perfectly. It will extend your barrel a little under 1 inch. The included compensator works pretty well to reduce my Hellcat’s snap. It is still snappy, but it’s quite a bit less with the compensator. The included thread protector is a nice touch as well. The self indexing compensator is pretty easy to install once you get the hang of it. I recommend watching a video on it.
