I ran a 34 in IDPA many years. KKM match barrel, tungsten rods, low recoil springs, trigger jobs right @ 2#. my advise is unless you are close to master level, save your money.
I was middle of the pack when I started and after a decade of shooting I was still middle of the pack.
with a torch and a drill/dremil, I can make a Glock trigger scare you, but I'm still middle of the pack.
crazy world we are living in.
