All Ruger single actions Grip Frame is NEEDED to fit properly!!
Ruger Single action grip frames can vary from gun to gun quite a bit. So it is always best to fit the grips to the actual gun. Next best is to send just the grip frame so I can fit it to them. There is never an extra charge for hand fitting because I do that to every pair of grips. Some models seem to be better than others and some worse. The Bisley is a must have grip frame period. Call me if you have questions, I know this can get confusing and no the old grips don't help me fit the new grips.
