I have a Mossberg Maverick HS12 Over and Under 12 gauge Shotgun (20")
and a Canuck Sentry Pump Action Shotgun (8+1)
I thought for sure the light weight 20" was going to hurt like hell. But it handles the recoil very well. And provides an excellent spread for nabbing gophers, and game birds.
The pump action runs extremely nice !! and the peep sight system om it works great !
Very happy with them both.
If your hs12 has the toe safety bet on having issues eventually
