Yes home defense. As far as pump vs. semiauto I’m thinking speed. I want to put the bad guys down asap. Seems kinda pricey though.
I’ve never shot a pistol grip like the 500 you mention. Wouldn’t it be hard to control, esp on 2nd shot for perp 2?
The Mossberg 500 Rolling Thunder has a can on the end of it they call a "barrel stabalizer" that weighs it down more. But, that is longer than the regular 500 tactical. It (500 t) surprisingly doesn't jump as much as you'd think. I've missed a clay bird and been able to rack, swing, and get it on the 2nd shot......that's at a small target moving away. You could certainly pump a shell of 12 ga Federal .00 into one perp, rack on the recoil and hit the second. I would have to test them together, but I wold almost expect to get less barrel rise onthe pump than a semi auto. And, you can add the fold over stock on the Mossberg. This way you could have the best of both worlds..the Mossberg is pretty quick on the rack. It all comes down to personal preferance, most likely scenario, and the balance in the pocketbook.
