The AmeriGlo Green Tritium Single-Dot Rear Sight for Glock (AmeriGlo part no. GL-143R) is an i-Dot style tritium night sight built for the full-size and compact Glock lineup, excluding the slim 42/43/43X/48 variants which use their own dedicated 2-dot sight. AmeriGlo’s single center tritium dot gives a cleaner, less cluttered sight picture than a 2-dot or 3-dot rear, which many experienced shooters prefer for faster dot recognition under stress. It’s compatible with MOS slide models as well as standard-cut Glocks.
