The one I shot (in '88, IIRC) was not so accurate. Less accurate than the G17s then available, less accurate than the S&Ws then available.
It's been a long time, but I recall benched 25-yd groups in the 4-5" range. I don't think we fired any ammo except 115-gr (all that was commonly available in '88), both FMJs and JHPs. My friend who owned the P85 (the gun store I managed had raffled it off in a drawing, and he won) qualified with it for Albuquerque Police Department, but the range guy was not impressed with it and suggested he move on to something else.
Not long afterward, my friend did . . . a S&W 25 in .45 Colt.
Personally, I would avoid the P85s and head for a newer Ruger model (if one is determined to buy Ruger).
