KS-23? Ammo is going to be hard to find for that.
Right now I use my good ole Mossberg 590A1. But I have my eyes on the Keltec KSG seen here: http://www.youtube.com/watch?v=Ae-aZnooe_8
If/when the bugs are worked out of the design and they become more available I'm thinking about picking one up.
i heard the Kel Tec KSG is Cali-legal. I can't confirm that so I guess I'll have to wait and see. If its cali-legal I'll be picking one up too. I want a 12 gauge but I don't want something else one else got already.
ideal "boomstick" for me would be a double barrel pump shotgun, seeing that none exists currently, I think I'm gonna have to build one then. The Remington 1740 isn't really double barrel pump gun, its just two shotguns bolted together. I'm talking about a gun built specifically to features two barrels, dual action, two magazines and two of everything but receiver, pump slide, buttstock, and optics rail.
a double barrel pump has its advantages- 2X the capacity, 2X the firepower, less recoil per shot, and is epic cool. but its also a bit heavier and more complex.
on currently what's around, I'd like a S17 Tromix Saiga 12. 8" barrel, semiautomatic detachable magazine fed Saiga 12 shotgun.
