What does low and high mean for GLOCK® sights?

The simple answer on GLOCK sights would be:


LOW sights are for 9mm and .40 Caliber GLOCK pistols (models 42/43 excluded as unique sku’s for these two models).


HIGH sights are for .45 ACP and 10mm GLOCK pistols, with the specific exception of the GLOCK model 30S and 36 pistols.  We do not offer sights for these two models.


All GLOCK  pistols sights have the same height front sight, the difference in height is only applicable to the rear sight.
