I cut down the mag release buttons on my P95.
I called Ruger, and talked to a gunsmith.
He said "You wouldn't believe how many people call about that."
He was very helpful and sent me free replacement buttons, in case I messed up the originals.
He gave me the following instructions:
-All directions are given from the rear of the gun, with the muzzle pointed away.-
1. Eject mag and pull slide back, make sure weapon is not loaded.
(You should remove the slide at this point also.)
2. Push the mag release button on the right side forward.
3. Put a small screwdriver behind it and push. It should pop out.
4. Working through this hole, use small punch to hold spring forward.
5. Push left side out.
Reassembly:
1. Use punch to hold spring forward. (Working from right side.)
2. Insert slide-release button from left side. (May have to use mallet to tap into place.)
3. Push right side button into place.
Tips:
1. Get Carbide wheel for Dremel. Buttons are hard metal.
2. For straight cut, cut parallel to back of button.
3. Cut off all but last serration.
Getting the second button out was very difficult, and getting them back in was a bear, but I was able to do it, and am very pleased with the results.
I used a cutting wheel on my Dremel to cut some horizontal grooves in the new flatter buttons. Now they almost look like factory.
Good luck, and let us know how it goes
