Saw one of these in WalMart today. It had an 18.5 inch barrel, and cost $160 dollars. Don't think I can pass that up. I think I'll swing by sometime this week and pick it up. Questions- 1. I'm looking online for some aftermarket stuff - rear pistol grip, forend grip. I notice a distinct absence of such items for the Pardner, yet there are an abundance of such things for Mossberg 500 and Remington 870. I've read that 870 aftermarket parts work on the NEF, but want to confirm this before I buy. 2. Some of the grips and forends I'd like are listed as 12 gauge. Can they also work on 20 gauge or do I need to look for specific 20 gauge designated items? 3. How does 20 gauge stack up to 12 gauge as a home defense round? Can it get the job done?
