The only Glock that I owned that did not have night sightswas my model 36. That has been taken care of. I ordered some night sights from Glockmeister. Can't wait to install them. I was waiting for a night sight to come out for the 36 that I didn't have to grind down the screw on the front sight. The 36 has been my favorite carry weapon, but always wanted night sights on it.
