I've owned a DP-12 now for a little over a year. I have probably 1,500 rounds through it without a single malfunction. It is anything but a "novelty" shotgun, it is a serious tactical shotgun with a 16 round capacity/ Yes, it's heavy, but super reliable, and not ammunition finicky. It will shoot virtually everything you stuff in it. I've even got it to reliably function with 1 1/2 inch mini-shells.
