Low-recoil Shotguns

As has been mentioned here, if recoil is the primary issue (as indicated by the OP), then a semi-auto is generally the best way to go. Cost then becomes a factor.....he didn't indicate whether money was an object here or not. You can get a good pump, like the Remington 870 or the Mossberg for around $300, whereas a good auto-loader will run at least double that. Target loads, however, keep recoil levels lighter and are certainly adequate for home defense, and also not as likely to penetrate multiple walls as would be buckshot or heavy hunting loads. Slugs? Forget it. If you're going to do slugs, why not just have a more accurate and lighter recoiling 5.56 or 7.62x39/52 semi-auto rifle next to the bed?
