I've never owned a Glock before but am in the market for a 40 or 9mm doesn't matter a whole lot which but having carried a 40 as a duty weapon(s&w) I'm leaning towards another 40. Visiting the Glock website I see that they will customize a weapon for added $'s would this be a sweet deal or would it be better and or less expensive to find a local gunsmith to do a trigger job and add better sights in my area? Any ideas would be gladly considered,this weapon would be used mostly for ccw. Thanks...
