New sights on PX4

[Gripsafety]

I bought the Beretta adjustable sights for my PX4, and the job looks easy enough with a drift punch, but I'm asking first here if there are any landmines I'm missing. Are there any tips on replacing the front sight with the new one?

easy enough to do but the finish on the px4,s is thick. almost like a painted on type. the one change out i have done resulted in some chips around the dove tail from the sight itself being moved. no my drift did not do it. a birchwood casey touch up pen took care of the chips, just wanted to let you know it is a possible hic up.
