I guess I'm a little confused as to the question the OP is asking. Are you asking which method (IWB, OWB, FBI cant, straight drop)? Are you asking which gun? Or are you asking which available holster for a Double Eagle? Are you wanting suggestions for your use, or what we would use for ourselves?
My most comfortable holster for a 1911 is a Wilson Tactical, until I have to do something like sit in a car or at a desk. For that I prefer a canted holster, such as the Milt Sparks EX for a 1911. The EX doesn't have a secondary retention device such as a thumb strap, so I wouldn't use it for OC. For OC, probably the only holster I'd use is a Safariland ALS. It has a hidden retention feature, but it's bulky and straight drop, so I'd still be more physically comfortable concealing IWB with the EX if long periods of sitting are necessary. I guess I could use something like a Bianchi Model 7 OWB with thumb strap and forward cant, but I detest thumb straps for any carry that's not in uniform, and even then I prefer the Safariland ALS + rotating hood for extra security and ease of reholstering.
