Glock 17 Gen 4 9mm Night Sights
The Glock 17 Gen4 9mm Night Sights is a full-size, striker-fired semi-automatic pistol chambered in 9×19mm. It combines the Gen4 platform’s ergonomic upgrades with factory-installed Glock Night Sights (GNS), which use tritium inserts to improve sight visibility in low-light conditions. The Gen4 G17 has been widely used by law enforcement, military organizations, and civilian shooters.

Key Features

Night Sights
The “Night Sights” version differs from the standard model by including steel sights with tritium illumination.
Features include:
- Tritium inserts that glow continuously in low-light conditions without batteries.
- Steel construction for improved durability over Glock’s standard polymer sights.
- Same sight picture and height as factory Glock steel night sights.
Night sights improve visibility of the sights in dim conditions but do not illuminate the target. Positive target identification still requires adequate lighting.
Trigger
The Glock 17 Gen4 uses the Safe Action striker-fired system:
- Typical trigger pull: 28 N (about 6.3 lb).
- Consistent trigger pull for every shot.
- Short, tactile reset that many shooters appreciate for rapid follow-up shots.
Magazine
Standard magazine capacity:
- 17-round detachable magazine
- Compatible with factory Glock 19-, 24-, 31-, and 33-round magazines where permitted by law.
- In jurisdictions with magazine-capacity restrictions, 10-round magazines are available.

Considerations
- The Gen4 model has been succeeded by the Gen5, which introduced features such as an ambidextrous slide stop and other design refinements.
- The full-size dimensions make it less convenient for concealed carry than compact models like the Glock 19.
- Tritium night sights gradually dim over time and may eventually require replacement.
