Why can't anyone give me a straight answer?!? I ordered a G23 w/factory night sites from a local gun shop. He's getting it from a distributor on Friday. I asked if the sites were Glock's own "brand" or if they used a third party, Trijicon or Meprolight. They didn't know. I spoke to another gun shop and he told me he had ordered a dozen Glocks with night sites for the Pennsylvania Game Commission and he sent them all back because they were not Meprolights, which the Game Commission wanted. After searching these forums, it seems there are a variety of different night sites coming from the factory and the only way to tell is by calling Glock and giving them the serial number. Now this kind of pisses me off because I just spent $550 on this gun and I don't want just any night sites, I want good ones. The only positive outlook I have right now is that since the gun is coming with the night sites from the factory, Glock should off offer their lifetime warranty, right?
