Very nice pistols!
I abandoned 115 grain loads more than a decade ago. The modern 147 grain loads in standard pressure form do very well in my 9mm pistols. I also found that point of aim with my 6946 EDC is spot-on with 147 grain loads. I have used both Federal HST and Winchester Ranger T 147 grain ammo, both were accurate and reliable in my pistols.
