I'll say not for me and here's why. I'm very firm in my belief that a high capacity pistol is best for indoor work. Easier to do other things with a free hand and also, should you get jumped somehow, it's easier to keep a pistol pointed at the BG reather than a long arm. And also, my walls are thin...with a fully automatic, no telling who or what else will look like a screen door!
My M4 is the weapon of choice for outside work.
But the thought IS mighty tempting.....especially if I can have an H&K MP5 w/ 3 shot bursts!
