CCS:
This gun is a great buy anyways, and I'm sure it will shoot fine.
Good luck with it.
I also appreciate swivels as I hunt natural game on large areas too.

Re: the 2 screws on the belly: It's an easy way to do a quick sort when checking a large gun rack of SXS such as at auctions etc.
No screw is WR droplock, 1 screw is sidelock, 2 screws is the remainder.

Best regards,
