Molot VEPR 12 AK Shotgun: Five Round Mag?

I carry a spare magazine for my Glock 30SF. I don’t do so because I think I’m going to need more than ten rounds. I schlep a second mag because magazines are the weak point of most any semi-automatic you can name. Which is one reason why I’m not bothered by the fact that my Benelli M2 Tactical shotgun has a five-plus-one round capacity. No box mag; no box mag to fail. (Six rounds before reloading seems sufficient for home defense.) But if I was going to have a box mag-fed shotgun I’d want a custom Saiga with a ten-round Surefire mag. But then I’m a reliability guy. You? (PS Whaddup with the lack of Picatinny rail action up front?)
