vegas! you can drill the front sight yourself.i too was worried about installing a new front sight but it was easier than i thought.bought the right drill bit from cz custom,fitted their 1.5 mm fiber optic sight to the front groove,put the slide in a padded vice and the drilling went like a breeze.most sights that are metal are soft enough the drill walks right thru.your only taking a very small amount off of the bottom flat of the sight .i filed and fitted the front sight so a light tapping seated the sight firmly into the back of the groove and the pin hole drilled in place gives me the tightest tolerance possable to keep it in place.i use black electricians tape to cover any part of the slide or sights you want to protect and once the installation is complete just pull the tape off.
