I have a semi-automatic Remington 1187 with an 18" barrel. Just wondering why I would need a Saiga 12?
Have you ever shot / held one?
The Saiga is one of the very few shotguns that is actually pupose-built for killing "non-winged critters". Most HD / "tactical" shotguns are nothing more than short bird guns with tacticool paint. It's the only shotgun out there that the company had to add a bunch of crap onto it to make it LESS appealing in order to sell it. The recoil on a Saiga is LIGHT, the sustained (multiple mags) rate of fire is rediculous, the ergonomics are awesome, reliability is better than any auto I've seen, and they are very unique (something I look for in a gun).
You don't have to baby it, protect the finish, use specific ammo, hell, you don't even have to clean the bitch. If a Benelli is a prom queen, the Saiga is a biker chick. (Totally stolen from Sonny)
You can customize them to your heart's content, your imagination and DIY abilities being the limit. Additionally, everyone I know who owns a Saiga built it up to be what it is, that is that Saiga users are not afraid to open her up and start messin' with her. That is not because of the target market being bubba gunsmiths, it's just because they are so simple and tough you really can't screw them up.
Go ahead and grab yourself a neutered (sporter) S-12 and a dremel and tear it up, you won't be disappointed.
And to answer your question about need, you don't. But it sure is fun to have.
