Did you ask them if they would order one for you? Most will take a partial deposit and place special orders.I've used GunsAmerica for two or three buys. No one local had what I was looking for, so I bought off of them. Prices didn't seem any higher or lower than the other sites, and GA had pages more of the arms I was interested in.
Does anyone have a preference. It seems like the guns america is more pricy than gunbroker. I like Auction Arms the best. I guess if you search enought i.e. local shops, internet shops, friends it doesnt matter where you get it from as long its the best deal.
GB is a great reference for getting a ballpark on firearms pricing,
