The Williams™ 71033 Fire Sight is specifically designed to fit the Glock 42/43. Williams™ Fiber Optic Fire Sights offer shooters unmatched open sight visibility in low light settings. The fiber optic rods built into every Williams™ Fire Sight Set gather ambient light and reflect it back to your eye, enabling faster target acquisition. Williams™ Fire Sights do not use artificial light sources to create their sight visibility, making them legal to use in states that do not allow artificial light sources on your firearm while hunting. 

This Williams™ Fire Sight Set 71033 fits the following firearms:

• Glock 42
• Glock 43
