I bought a new Glock 19 it was about 454 with tax. The guy at the store said it would take 1-2 weeks to order it from glock and this was last sunday so i should have it by next weekend. Getting really excited to own my first gun. Any recommendations on sights i was looking at some small red dot optic sights but they are a bit pricey. Are these optic sights better then the standard handgun sights?
