septic tank bullseye in lawrenceville has that model 500 with a pistol grip in stock saw it 2 days ago. and id say shot gun. i have the mossberg 500 pistol grip in an 18.5 3 loads of 00 buckshot and 3 slugs. Sits next to the bed with a glock 23 and a walther p22. The p22 i can pop off 11 rounds in 3 seconds all on target no recoil what so ever. The 40 give me 10 seconds to unload all 14 rounds, and the 500 just shoots through walls haha. But as far as a home defense weapon anything that your comfortable shooting and are on target with. You could spend all day arguing what guns best but in reality its what best fits your shooting abilities and how accurate you are with that weapon. But you cant go wrong with a shotgun. Usually youre gunna hit the intruder unless your just the shittiest shot in the world.
