A 10 Gauge? Not!!!! Jager, wait until you shoot one especially a double barrel or pump! Probably one might even wonder after the shot who got the worst end of it? You or the perpetrator!
I will tell you a 3 1/2 12 Ga Mag is bad enough. But for home defense certainly a standard 12 ga pump with 4/0 or BB or No. 2 shot is a better choice by far. And something about racking the slide on a pump gun telegraphs a world wide recognized sound to most all bad guys! I literally had one mess his britches (#2) when the gun was pumped on one occasion before my voice command! LOL!
It is a universal sound!
