The compact 1911s I've seen do have their problems. If you can find one that works, great, but I'd want to shoot it first. There's nothing like buying an expensive gun, going to the range and having the thing not work. Then you have to box it up, send it back and wait forever.
Many 9mm pistols work right out of the box and I prefer them with a good JHP (Remington 115gr). You can also get +Ps and I think the stopping power is better as well.
The 1911s were fine in their day (they normally made 'em a bit loose so they'd work), but once they're tightened up they many times need work -- too many times to be comfortable without the option of first trying them out. Zunfoldge's gun is the better way to go if you must have a .45ACP.
Just my opinion....
