Gunsmith and Glock........ Two words to never mix :-) Seriously don't ever let a "gunsmith" work on a Glock.
Glock sights are real easy to install, you just need to find someone that has a sight tool. Takes 5 minutes.
If you want to set up a time with me and make a drive all the way down to Syracuse (45 min south of Omaha on Hwy 50), I would put them on for free.
If you want to get them done closer to home, I would recommend checking with the Bullet Hole, they can likely do this for you.
