I got to shoot one at the HRA annual meeting. It handled well, pointed quickly, and broke clays. No malfunctions in the 10 rounds I shot. Honestly, it was far from the sweetest 12 gauge I've ever shouldered, very middle-of-the-pack. If it weren't for the detachable magazine system, I'd never give it a second look.
But with that detachable magazine, and particularly with the drums, I think we've found the king of zombie survival tools!
