Yes, I have a Williams Fool Proof on mine. Williams makes one for the 9 (FP-M9). You will still have to go with a higher front sight. Go to www.williamsgunsight.com and you will be able to find the right height front sight needed. I had several thousants milled off of the bottom of my sight where it sits on the receiver but still had to use a higher front sight to get bullets in the bull. It is relatively fast, even quicker if you take the aperture out and use it as a ghost ring. Even so, I'm still thinking of going to one micro dot sights like the Bushnell or Jpoint. If you go with a Williams you will probably need to cut a notch in your stock for clearance, I had to.. The Skinner wouldn't need this, but I didn't know about Skinner sights when I put the Williams on mine.
