I hope the OP won't mind me butting in a little bit...
Are there any "value priced" double stack or wide grip 1911/2011 offerings? $1200+++ is not acceptable for an STI when I can buy a polymer pistol just as capable for half that or better. But I do LOVE the ergonomics and look/style of the 1911. I just don't like their minuscule capacity.
Rock Island Armory has a double stack, it's hit or miss finding them. There are several companies that are making 2011's, I believe a company called enterprise would be a good one for you to check out. Also, I would say check out Fusion, they have plenty of parts to build your own in any flavor you want. Para ordnance also has one, but it has a ton of negative reviews, both for not feeding ammo correct, and issues with the DAO trigger assembly.
Or, you could simply go get a 10 or 15 round mag for a single stack.
