Height: .215", .235" and .250"
ALL Glock models, regardless of size, caliber, or generation, most commonly use the .215" front.
Glock 34/35, 41, 17L, 24L most commonly uses the .235" front. Sights do not overhang slide cutout.
Glock 48 uses .250" front with our GLOCK MOS STANDARD HEIGHT REAR SIGHT.
The .235" front lowers impact approximately 2-3" at 25 yards relative to the .215" front.
The .250" front lowers impact approximately 3-5" at 25 yards relative to the .215" front.
Please note that different guns will vary in regards to point of impact, especially with differing shooter preference. These heights are recommendations, and we cannot guarantee point of impact due to variations in individual guns. Point of impact will vary by *individual gun* and not so much by generation.
