Thanks again for all the information.
The sku number of the one I'm looking into is IZ-107. I still need to verify the "muzzle adapter".
Tonight in my bow stand I'll ponder the purchase. Overall, it sounds like an awesome shotgun. Even if i end up using my 870 express for waterfoul, i'll be OK. (I'm still going to try with the saiga though!) I think the shorter length of the saiga may be slightly better for the dense cover I hunt grouse in. Hey, the price looks right to boot!!
