Description

The AmeriGlo i-Dot Tritium Sight Set is a replacement iron sight kit for Glock pistols, designed to give the shooter a quick, consistent sight picture in low light. It uses a dot-over-dot layout, with a front sight and a rear sight each carrying a tritium insert for self-illumination without batteries.

The front sight is a ProGlo style with a green tritium dot and white outline, and the rear sight is a single dot design. Both use tritium, so the sights glow in darkness without external light. The set is listed for Glock Gen 1-4 pistols in the 20, 21, 29, 30, 31, 32 and 36 models, and for the 10mm Auto, .45 ACP and .45 GAP calibers.

  • Calibers: 10mm Auto, .45 ACP, .45 GAP
