STI and Remington have them. I’d sure love to see Ruger offer a double stack 1911. I’d buy it! Love my Lightweight 1911 Commander. I think they should offer options for a threaded barrel and RMR optic mount too on their 1911s.
I've had a few double stack 1911's.........2 PARA's and a couple of Remingtons. A little heavy but 14 + 1 round of 45 acp is hard to beat!
