I am thinking about putting a red dot sight(C more) on one of my Glocks. My only concern is that all 3 of them (17L, 19, 22) eject straight up. A mount may be a problem for them. Glockmeister has a mount they claim doesn't interfere with ejection, but I don't know if I should believe that. I know you can have the ejection port lowered or extractor changed, but I would prefer not to, it's not that important. Any feedback would be appreciated. Thanks!!
