391 xtrema 2 with KO

[.50cal packer]

I was recently looking at a new beretta xtrema 2, and found that there were a couple of models. One with a "KO" and one without the "KO". My problem is that beretta doesn't say what the KO is. But for around $400 more it better be worth it. Does anyone know the KO is and what it does?


Thanks

I just bought one with the KO and it is a FANTASTIC gun.

I bought one with the KO about two months ago.

Wow, what a shotgun! I shot 250rnds the other day of 12ga 1200fps 1 1/8oz and did not even feel it. I also own a Benelli SBE (awesome gun) that in my opinion feels like it kicks way more! Just my .02cents

I beleive the KO = kickoff reduction system that lowers the recoil.
