Last week we ordered a G43 for my wife. The distributor my LGS buys through said there were no G43s with factory night sights, so they ordered a set of Trijicon night sights to be installed at the store. The pistol arrived and they attempted to install them, but they did not work. They were unsure as to whether the sights were not properly machined or the slide. The guy who I am dealing with is not in today, but he has spoken to Trijicon and also plans to call Glock tomorrow. Has anyone else bumped into a problem like this?
