Description
The TruGlo TG131G3 Brite-Site sight set uses traditional fiber-optic elements to provide bright, easily acquired aiming points in a range of lighting conditions. Each sight is housed in a CNC-machined steel body with the fibers concealed to reduce visibility from the front. The low-profile, snag-resistant design is intended to fit standard holsters and preserve the slimline profile of compatible Glock pistols.
