If you just want a shotgun ... well, it's a shotgun
. And yes, I have one, so I'm not making fun of them.
If you have other AK style firearms and want an AK shotgun, a Saiga will definitely meet that need. A 12 gauge AK - how cool is that?
If you want a blaster for the range - it has that role down pat.
They make pretty good 3-gun shotguns, in the eyes of some shooters.
Some people do use them for HD. I'm not comfortable enough with keeping plastic box magazines loaded over the long term to be one of those however.
The 'gun club' crowd would have ... mixed reactions ... to it, I'd guarantee.
There are many better choices for hunting.
Like everything else, it's not a one dimensional choice. Its appearance will alienate some people and attract others. It is definitely a 'statement' shotgun - be sure you know what it says, and be sure that's what you want to say... especially if it's the only shotgun you have.
fwiw...
