This is a Smith & Wesson CS40 slide assembly that includes the barrel, guide rod, and recoil spring. The barrel has been reamed out to 10mm. The recoil spring has been changed out to a 22lb spring. This can go on a Smith & Wesson CS45 or CS40 frame.
All you need to go with this is a CS40 mag converted to 10mm. I may have some extra mags that I could convert at an additional cost. I have not test fired this slide, but I have two others that I have used and have not had any issues yet with about 150 rounds so far.
