      Great kit even for the Police Magnum

      Posted by James Allen-Levesque on 27th Mar 2026

      I got this kit for the Police magnum and even though I don't need the carrier spring, it's always good to have extra! The rest of the kit was easy to install and now my 870 looks just like the one I used in Rainbow Six Vegas 2 when I was a kid. Bonus that it's usable for duty too!
