I have the Skinner on a No. 1 in .458 win. As well, I have several on Marlin 1895's. They are very well made, shoot great, and the customer service is fantastic. With the Ruger, I use it with the NECG sourdough post front sight (skinner doesn't make theirs for a No.1). I have used the XS site and the NECG, I would say the Skinner is my first choice for a peep sight (NECG next).
Good luck.
