I know they discontinued them to make room for some of the new models. You'd probably have to check with the gunshops around you and have them call their distributors to see if they may still be able to get them.
I tried GunBroker. 1 auction is closed, the other is open for 2 hours, and my dealer is closed until tomorrow morning. ??? I'll take a chance my dealer can get one out there somewhere. Meantime I'll keep looking, ncluding GB.
