To each his own. I'll take my 20 ga or 12 ga with an 18 inch wide open tube with #6's or #4's with standard 2 3/4" load with low brass. I don't need sights and I'm not worried about over-penetration except as it pertains to me.
I've never fired a gun in anger ever. I did however have to rack a round into the chamber when I lived in a shady area of Detroit. The shady person beat feet faster than I could think about shooting. I'm decent with a pistol but will always hit anything at 21' or closer with a scattergun.
