I have both new models 63 8 shot and the SP101 8 shot. The quality and accuracy is good on both models. Both have fiber optic front sights, red on 63, green on the SP101. The trigger was tough on both when new, but replacing the return spring can fix that. The one thing I don't hear any discussion about is the difference in grips, trigger and frame design. Comparing out of the box on both 8 shots, I find the 63 fits me the best. The SP101's grip is too small for my hand and the different frame design (wider frame/thin trigger) causes my trigger finger to hit the frame when firing. A larger grip may help the SP101.



I like the Ruger but it does not fit my hand well with the stock grip, I haven't tried any other grips yet.
