I have one too. Word of advice, buy a couple of boxes of #00 buckshot to run through the gun first. I bought a case myself, 150 rounds.
I tried to run #7 1/2 through it at first, wouldn't cycle the gun.
I ran 30 rounds of #00 through it fired from the shoulder, perfect!
I ran another 30 rounds fired from the hip, a frickin' blast!
After that the bird shot cycled just fine.
Remember, stock they have a 2 position gas system.
#1 is for buckshot, powerful loads.
#2 is for whimpy stuff.
Don't fire buckshot on the #2 position, it will eventually damage the gun.
As for home defense, not my choice of weapon. Too long and cumbersome, but is a blast to blow stuff up! I need more #00!
