Is there some way you can borrow/rent a 1911 pistol to try it out? (I'm assuming you have little "trigger time" with this design, based on your other recent thread.)
I've tried just about everything out there handgun-wise, and just don't shoot anything else as well as a single-action semiauto such as the 1911 or Browning Hi Power. Almost as well with a Glock or XD on a good day, but not quite.
In truth, for self defense purposes those newer guns are more than sufficient if the shooter does his part though, to be fair. But there's a reason (the trigger! ) that 1911s have been at the top of the pile for so long in many different shooting competitions.
Whether that matters enough to you to spend the money ain't my call, of course.
