Adam I went through the exact same issue you are having a year and a half ago. I had some pretty high end pistols and I am not sure I would say you have to spend big bucks for reliability. Without finger pointing, I've had issues with some of the priciest guns made.
My other issue, my personal point of view, is I am not comfortable carrying a 1911 with the hammer back, safety or no safety.
I think CZ, for example, makes some excellent single/double action pistols that are great for carry. Also, the PARA LDA has an amazing trigger. I have a .45 with a 3 1/2 inch barrel that holds 12 rounds.
I shoot USPSA open and limited. I own a lot of handguns and the two I use for home protection and carry are both revolvers, a .45 S&W and a Ruger .357. No springs, no jams to worry about and pretty much totally reliable.
