Well, I was at the shop a couple months ago, and a guy was positively drooling over a similar looking gun, without the collapsible buttstock.
It was, however, a Benelli, and it runs about $1700. For TURKEY?
I mean, a Benelli might be the best thing going for high-volume doves, but why in hell would you pay an extra grand for the Benelli action when you're shooting TURKEY? A pump gun will do just fine, and even the super-duper turkey special from Remington or Mossberg is $1000 less. I guess I can see getting a gas gun for recoil absorption when shooting heavy turkey loads, but the Benelli doesn't do that anyway. Besides, it's just one or two shots. Get a Limbsaver and go hunting.
WRT porting... It's flat-out BS. The pressure curve of a shotshell is such that it doesn't do much of anything but make noise and foul up. I've shot many double and triple shots through unported guns, and the muzzle doesn't rise anyway, if the gun fits. A properly-fitting shotgun (on me, a stock 870 or 500 fits well enough) will recoil back, not up. Rise is a non-issue, even for clays doubles, and regardless, the porting doesn't help any.
Also, I'd hate to wear hearing protection while hunting, at least in most situations. Doves, quail, turkey, you name it, you generally hear 'em before you see 'em. Hunting without hearing? How does THAT work?
