Let me start by saying I’m one of the few gun people who actually likes shooting pistol grip only (PGO) shotguns. I liked it before the Shockwave grip, with reduced recoil shells, and I really like it now that guns like the Remington 870 TAC-14 and Mossberg 590 Shockwave shotguns are on the market.
But I’ve been wrestling with the idea of keeping one at the ready for home defense. No matter how much I practice with it, I just don’t feel as confident with the stockless pump gun as I do with a stocked shotgun. A laser sight helps immensely, but I don’t like being completely reliant on that little green dot.
I’ve practice actually aiming the Shockwave in an odd kind of high stance that I’ve found comfortable, and I’ve gotten pretty good, but I can never quite get my position to both feel stable and like I can use the small bead sight. A red dot on a small riser makes it a bit easier, but that’s another thing to turn on, and the idea of a home defense shotguns is supposed to be simplicity and devastating effects on target.
Plus, there's all the PGO shotgun haters out there and they have some compelling arguments.
A full year ago, InRange did a pretty solid comparison of a traditionally stocked pump gun, a PGO shotgun, and an old-school double-barrel exposed hammer coach gun.
