Got a question for those that own the Ruger Standard Models with the non adjustable sights. At 10 to 15 yards are they factory set for a 6 O'clock Hold and .22 High Vel. ammo? Despite being older than dirt I have owned only 1 Standard Model Mk I with a 6" barrel when I was a teenager. Some prior owner had filed the sight down I guess to make it shoot higher and that is the only one I ever shot. I afterward went to the target version's and never looked at a Standard again. I am thinking about looking at a Ruger MK II Standard in a 4" stainless so wondered about the sights. Thanks!
