Unreliable 1911’s?

I’m looking at a 3″ barrel 1911 for conceal carry. I’ve heard they are unreliable, any opinions?

I am looking for a good CCW jacket for all-around wear. Any suggestions?

When a police officer checks your drivers license for warrants, etc. does it give him information on whether or not you are a gun permit holder? I’ve heard some states put the information on your drivers license itself that you are a gun permit holder. Does anyone know what states do this?
