I purchased a used SP101 in .22 for my wife (Her fingernails were not compatible with a semi-auto).
The adjustable sights are rudimentary, but adequate. I would not consider fixed sights. Trigger was good stock, but the effort to cock in single action was heavy. I tried custom springs, but be careful and stay above the misfire level. It shoots better than me at 25 yds. As with all Rugers, double action shooting requires that the trigger be COMPLETELY released before trying the second shot. That last little "click" is important or the trigger will not function. My Taurus doesn't have this problem. Maybe the trigger spring forces you to the end of travel.
