I finally figured out that I wanted/needed some suppressor sites for my 226. My new sites should be here in a few days but I am wondering if there are any hints, tips, or tricks to taking the old ones off and putting the new ones on?

I watched a Youtube video on it and the guy just used a punch and drove the old ones out and the new ones in. Seems simple enough.

Any tips though to get the sites adjusted?

Based on Youtube it doesn't look like I am getting into some big crazy 'professionals only' type project but if you guys have any tips please let me know.
