Definitely use the 1911 at the CCW class. The shooting test shouldn't be hard but why make it more difficult than it needs to be?
Also, why not carry the 1911 as well and save both money and not add a new caliber that you have to stock? With a good holster and a good belt you should be able to conceal it adequately. Or, if you really like the 1911 platform why not pick up a 1911 "Commander?"
Breaking away from .45 ACP, the Sig P238 is like a mini 1911 as well... Although I'm not sure how I feel about cocked and locked single action firearms for pocket carry...
I'm a bit skeptical of the little pocket nines. We have a pocket Taurus TCP 380 for deep concealment and it is both finicky with ammo and difficult to shoot well due to the short sight radius, light weight, and marginal trigger. A compact M&P, Glock 19/26, or similar seems to offer a lot more gun in a fairly concealable package. If I were to get another deep concealment pocket gun I think I'd opt for a .38 snubbie.
