Actually I was in American Fork, but PG is close enough. :smile:
Does your friend happen to work at the Salt Lake airport?
I'd prefer to see the frame and slide before quoting a price.
The "pinch" method involves squeezing the slide in a vise, and peening the frame.
I do not offer this modification as, IMO, it is not as durable or precise as other methods. It is very difficult to get the slide rails straight and parallel. The peening and squeezing imparts stress on the frame and slide. The bearing surface of the frame rails is reduced when the rails are lowered by peening the slide rails.
A good fit can be achieved using this method and it is quicker, easier (though not really "easy") and relatively economical.
The weld and machine method offers a better fit, maximum bearing surface, and greater durability.
Another good option is the AccuRail system designed by Bob Krieger. This involves optimizing the slide and frame dimensions, followed by installation of hardened steel rods in the frame rails. The slide then rides on the rods. When the slide/frame fit degrades, it can be "readjusted" by the user in about 5 minutes by changing out the steel rods.
HTH.
