Screw on ammo "cuff"
Choose from 4 or 5 round in 12 gauge (or click custom and tell me about your rimmed ammo)
NOTE: Black only for the moment. You'll need to supply the screws and such (check your hardware store, I like the stainless steel offerings).
ETA: Custom made for each order. I'll email you when it is on the bench ( usually under 2 weeks with my current backlog).
