We had a couple of SP-101 2005 or so, a 2 1/4" and 3". Both those barrels were on straight. Both shot POA/POI at 25 yards and that short one was dead on the money. The biggest aggravation with those revolvers was sharp edges on the trigger guards and/or trigger, as well as that damn plastic insert that goes in the grip. Once those things were corrected, they were great little revolvers.
I have to wonder if Ruger figured perfect barrel index wasn't quite so important with the adjustable sight model.
