Morning. I had the slide in a big vice, card board wrapped, and went right to left as you're looking from the back of slide. I used a 2lb hammer and a solid brass punch. I had to hit it pretty hard to bust it loose. Once loose, it drifted pretty easy. Also, make sure you knock out the front sight pin and file a little off the top of the barrel bushing. Makes it much easier. They use some kind of glue on the rear sight that works very well. Haha. Good luck to ya and I hope this helped.
