Gentleman on the Beretta forum by the user name of Stormhawk has a lot of 11 round blued mags for sale. I bought 4 from him for $10 each shipped. He said he fell into a deal and bought like three ammo boxes full of them. Great guy and a good guy to deal with. He lives in Yuma AZ.
I have some mags that I don't need any more. I want to say two factory 11 rounders and one or two 10, one might be a mecgar. Sold the pistol a while ago and don't need the mags so I'll give you a sweet deal. Pm or email me if your interested and we can work out a price.
