Thanks Chris. I just got back from the range and the Precision One's XTPHP's worked perfect. I also tried Fiocchi HP's, Fiocchi FMJ's and Hornady American Gunner XTPHP's. All performed without a hitch. I tried shooting this gun off-hand as I will carry it as a back up most of the time and surprising to me was that I was more accurate off-hand. Probably because I haven't developed any bad habits with that hand. So far I've not had a problem with any brand or style of ammo in either my 3AT or the P11.
