I'm working with a police trade in 870 12 gauge magnum (takes the 3 inch shells). It's fairly old and I really dont mind having the stock capacity but if I can get one more shell out of it I'd like that. A few people recommended wilson extensions or OEM but I'm having issues finding the OEM and I'm not sure if the wilson combat one is worth the money.
Any ideas guys?
