Love this gun and it's flexibility. So many reviews out there I don't want to muddy the water with my input about the gun. A couple items I didn't catch on other reviews. It was packaged with 3 choke tubes (Full, Modified, and Improved Cylinder), a strap, and an extra ball joint for a strap connection. I did see a lot of reviews on the recoil for this gun. Honestly didn't notice it (until a day or two later which was just a little deep tissue soreness).
