Is there a certain side of the slide you have to push from to remove factory sights, and do the new ones go back in the opposite way? I just ordered a sight tool and new sights from midway and could use the help..
left to right, always left to right to remove sights, pins, etc. Install them right to left. If you are having trouble getting the sight to move (some are staked in, some are LocTited in), take it to a gunsmith, not to the vice and hammer.
