Great suggestion. I'll keep checking that.
Does anyone know if a Glock 19 G4 needs "high" or "low" sights?
Glock 19 standard rear sight height is 6.5mm or (thanks to google) .255 inches. Most of your after market Glock sights have a similar height available. If, like me you have 10mm or .45 Glock then you need the higher sight 6.9mm or .271 inches. Just FYI Glock makes 3 sizes of rear sights. 6.1mm, 6.5mm, and 6.9mm. Glock factory front sights are all the same height.
