I’m thinking of getting a shotgun for home defense, possibly two, one for my wife and I. I’ve done some research and really like the Mossberg 590a1. I’ve also looked at the Winchester SXP Defender and the Remington 870 Express. I like the shorter barrel lengths like 18-20”. Are these shotguns good choices? Are there others out there that are better options in the $300-600 price point? Was thinking maybe 12 gauge for me and 20 gauge for my wife. We’re totally new to guns. So any tips or suggestions would be greatly appreciated. Thank you!
