No worries. Glock has made 5 generations of there pistol line. But the 43 was a new design for the gen 4s. Therefore that’s what it was listed as. Just because it was based on the gen 4 glocks alreadyMy mistake.....that's what I get for ASSuming....Why in the world would somebody make one generation and call it Gen 4? I need to do my research before chiming in I guess.
