I have one of them. Its actually a Russian made shotgun that will shoot light loads to heavy loads, from 2-3/4" Shells to 3-1/2" Shells. Its a good field gun with an adjustable gas system (to allow you to shoot light loads to heavy loads). Mind you, these are no beauty queens to look at, but just all business.
The gun works great for Dove Hunting/Duck Hunting. (I've only used mine for that so far). The only issue I've had with it was trying to find a sling plug for the front of the magazine tube. I ended up having to drill out the stock one and putting a sling stud on it.
Personally I like the shotgun better than my 390, just because if I fall into the mud or the water (which can happen with duck hunting), I really don't care if I get this gun dirty, wet or scratched.
They come with Steel Full Choke, Steel XFull, Steel IC, and Steel Modified.
