Dude, don't know what you traded for that but, damn, that is a fine kit you got yourself right there. Better than the SPX version IMO if you take that rail off the top. Specifics I don't know w/out closer inspection tho. I wouldn't worry about the breacher in the way it is configured with that shorter barrel for HD. The 930 was Gun of the Year a couple back...
...but finicky w/low-powered ammo and clean it thoroughly first, then keep it relatively clean going forward.
Safe n fun shooting!
