MGW Sight Pro is what I used. The sight shoe for the 92 also comes with a spacer to successfully clamp the slide so it is being secured by the rail slots as well as downwards pressure from the top of the slide. Not the cheapest, but probably the best sight pusher. Rear sights are a little bit tough still because the decocker levers can get in the way of the side supports that the sight pusher has, but I figured out some ways to make it work.
