Phil, This is what I went with per UC's recommendation.

I did three of them, and only one worked out perfect. The problems that I ran into were

1) pressing the dovetail sight into the ramp was way too tight. Looking back, I should have used a small, fine file on the front sight so it wasn't so tight.

2) the screw provided with the ramp and the original screw are too short. I think they only grab about 1 thread.

So, I ended up with 2 of the guns having the original ramp with the new sight. For the screw, I used one of the screws from the original back sight and cut some of the threads off so it wasn't too long. I have yet to shoot one with the higher ramp and new sight. I know it will be ok, just the back peep is a little higher than it needs to be. The setup with the new shorter ramp and the shorter front sight is perfect in my opinion.

Yes, I completely butchered this job, but all three are fuctional. I am going to leave everything as-is for now, but will redo the 2 of them after hunting season.

By the way, I do not have one of the tools to press the dovetail in and out, I just used a brass punch/hammer.

I highly recommend trying to get a longer screw for the ramp if you decide to change it out. Local gunsmith probably has them. If it's too long, just cut/grind the excess off.

Let me know if you have any other questions, might save you some of the agony I went through.
