The Mossberg 590 Shockwave is a solid self-defense gun. It's got some key features like an ambidextrous safety, dual extractors, and a strong lockup. The pump action is smooth thanks to the twin action bars and anti-jam elevator. Plus, it's got a heavy-duty 14-inch barrel, a comfy grip. Pretty straightforward setup. Missing the front bead sight as well as having a few scuffs.
