You are buying a weapon for home/personal defense.
Everything else is a supporting disipline.
Ergo, you want a Colt model 1911. A service piece with minimal competition mods; Bevel the magazine well for better reloads, put on a pair of grips that work for you. Port it.
Anything else is destined to eventually break. You can stand that on the range, but not at 0200 with a big guy between you and your wife.
Load it with a brand of hollow point that you have tested IN THAT GUN and with which you don't get a single feed failure in a box of ammo.
Compete in Tactical class. Let others spend a gazillion dollars on a space gun. Practice and compete with 200 grain reloads boosted to make major, but put a box of ball through it occasionally so you don't forget what you're holding.
Practice, practice, practice. If you don't fire 100 rounds a month, you're better off with a shotgun.
Good advice
