I can't explain it. I had the clips set up for the lowest ride and the corner of the slide printed more than I was comfortable with...with both G26 and G19.
I really was pretty much set on sending it back when I decided to try out the loops I had in the shop downstairs. Didn't think it would make an ounce of improvement so you can imagine my surprise.
I have the PTDs set up in the highest set of holes for the lowest ride. I didn't measure if there is a difference in ride height with the clips in the lowest ride position vs. the loops.
