Since I don't load 9mm, I have been using cheap Tula 115gr that goes for about 14 cents per round for PCC. We use it in all of our rental sub guns and although a bit dirty, runs flawlessly and is sufficiently accurate. Is supersonic, so no problems with the shot timer. PF is around 140 from what I have read. Will have to chrono it one of these days.
Thanks for the info about the barrel. I'm going to order one..
