26.1" overall length. Try getting that on a Saiga with a stock and not having it be an SBS. This is an advantage in hallways.I don't see how this is as Good as Saiga for HD, and for shotgun games or hunting its Useless
14 rounds without a wide drum or extremely long box magazine allows it to fit into places better.
Able to switch between two loads with minor effort (swap over, rack slide) if you have two different purposes (i.e. out in the woods, buckshot for two-legged predators or slug for four-legged).
If the above QC problems are real (I haven't actually played with one in person) then I can see the problem, but there are real advantages to this design.
Caveat: with that said, I see the benefit of the Saiga. Faster reloads (although honestly, with 15 rounds, you *shouldn't* need to reload), more after-market parts available, more gunsmiths are likely to be familiar with this product.
