Damn, I bought one yesterday and I didn't ask them to change the night sights, BUT, my hats off to Glock. When he came back with my gun, all the internals were changed out, all new (7) magazines, and he updated my Gen 4 23. All for free. Great company and I will continue to buy their guns. Glad they are in Georgia, creating jobs and helping the econmy out.Yes - but when you buy one of the police trade-ins you need to make sure the are night sights on there are actual Glock night sights. Their sights carry a ~10yr warranty. If its dim you can ask them to replace it.
Glock puts their logo (in very small letters) on the sights.
Outdoor Adventure customer service wasn't bad surprisingly, since I hear so many negative comments about them. The only thing that sucked was checkout took too looonnnggg, and needing three people to check the paperwork was a little bit much.
