I don't know about the double stacks but there 1911s for the money are pretty good guns. I own 2 of them. The 3 1/2" cs and the 9mm TAC and both are great shooters. In fact the cs is my primary carry gun. CS is great as Ivan will take care of you.
I have the RIA 1911-A1CS. Had some problems when I first bought mine. It would not feed anything I tried, not even ball ammo. I was a little upset, so I sent it back. 3 weeks later they sent it back. WOW, what a difference it was. Now it will eat anything you feed her.
The price, quality, and customer service, makes pistol a great buy.
