I believe it is.
I've owned 2 of those guns with 4 magazines and the best I could get is the one shotgun feeding the next round "much" of the time. This was with a good dozen different brands and types of 2 3/4" slugs and about 10 various 3" slug types. I was lucky and bought the guns cheap enough that I about broke even selling them, even after stating why I was selling them.
Other than the feeding issue, they were accurate guns. They were probably the least fussy in regards to ammo that I have owned. If I would have considered either of them as a single shot rather than a repeater I probably would have been satisfied with it.
