Keep in mind two things. First that in an autoloading pistol (unlike a revolver) the chamber is counted as part of the barrel. That means that with 45acp a 3" barrel is roughly equivalent to a 2" revolver. That's not much room to accelerate. Second most 45acp is designed for optimum expansion when fired from from a 5" autoloader. Now I haven't velocity tested different barrel lengths myself but I've read figures as high as 10-13% when dropping from 5 to 3" vs 3-5% with a 4" - that's from my failing memory so don't take those figures as gospel. I've also discussed this on another board with a noted expert on bullet performance and terminal effects who expressed a lack of confidence in 3" 45acps and the resulting reduced velocities. Reduced velocities = reduced expansion.
It sounds like you have your heart set on a 3". I'm not really sure why because they're no more concealable than a 4" CCO. They share the same grip length and that's the key to concealing a 1911. But if you can live with the compromises then go for it.
