Initially, the HiViz sight was a little too loose in the slide dovetail. I located one of my old, unused feeler gauges that I didn't need any longer. I found one of the blades that I thought was the correct thickness to use as a shim and cut a small piece off using tin snips. I put the slide in a padded vise and hammered the new sight/shim in with a stout brass punch. I did use a drop of RED Loctite in the dovetail just for added security.
It probably took me about 30 minutes for the complete project from beginning till end.
