As little as I've practiced in the past year I'm now a big fan of running 185grn bullets in my 45 (compguns) 1280fps. With Softish 9mm recoil.
Whatever you do don't ever shoot a real comp gun. You'll be forced to own one!
I got my last one for $1300.00 total, but that was starting from an already fit range officer, and even then I had to call in a lot of favors. It's only single-stack.
Honestly that 34 will prolly shoot as fast maybe, maybe faster if you're on that day. It won't feel as mechanically cool, prolly won't have a 2 & 3/4lb trigger, and will have less horsepower per shot, but it'll also hold more, and it'll be easier to get, won't require all that fitting n what not.
