These are the rounds I've found best for me Glock 23, 27 155gr Rangers in summer 180gr Bonded Rangers in cold months Kimber 3" 185+p HydraShoks Glock 21 or Sig 220 230gr Gold Dots S&W 642 158+P SWCHP
G19 has the best accuracy with Gold Dot 124+p
P228 is a toss up with Golden Saber 124+p, or Gold Dot 124+p
P239 9mm shoots best with Golden Saber 124+p
P239 .40 is loaded with Golden Saber 165gr
And on rare occasions when I carry a P230, CorBon 90gr is my choice.
Winchester Ranget RA45T, 230 Grain for my XD-45, but I've also got Hydra-Shoks, TAP +P, and HST laying around in .45 too. The XD has worked fine with all of them except for the first box of Hydra-Shok's I put through it.
I am carrying 230gr. Golden Sabers in my Springfield at the moment. I also carry 230gr. HSTs.
I carry 90gr. Gold Dots in my P3AT as they have proven to be 100% reliable in it and when chronoed they are going right at 900 fps out of the tiny KT. Not bad IMO.
