GLOCK 17/22/31 Generation 4 w/TLR1®

Pairing a Glock 17, 22, or 31 Gen 4 with the Streamlight TLR-1 (or the 1,000-lumen HL version) creates the "Gold Standard" for North American law enforcement duty setups. This combination balances a high-capacity, reliable handgun with a legendary, combat-proven weapon light.

The Gen 4 Advantage with a Light

The Gen 4 series was specifically engineered to solve a rare issue seen in some Gen 3 Glock 22s: reliability failures when using heavy weapon lights.

• Dual Recoil Spring: The Gen 4's dual-spring system alters the slide velocity during recoil. This ensures that the extra weight and rigidity of a clamped-on light (like the TLR-1) doesn't interfere with the cycling of the frame, making these models significantly more reliable than their predecessors when "kitted out."

• Standard Rail: All three models feature the universal Glock accessory rail. The TLR-1 includes a set of keys; you should use the "GL" (Glock) key for a perfect, play-free fit.

Holster Compatibility (The "Light-Bearing" Rule)

Once you attach a TLR-1, standard Glock holsters will no longer fit. You must look for holsters specifically molded for the light, as most modern light-bearing holsters achieve retention by gripping the light body rather than the gun's trigger guard.

2026 Recommended Holster Options:

• Duty (OWB): The Safariland 6360RDS or 7TS Series remains the top choice. These use the ALS/SLS system and are designed specifically for this exact Glock/TLR-1 combination.

• Concealed Carry (IWB): Vedder LightTuck or Tier 1 Concealed offer Kydex options that accommodate the TLR-1 while keeping the profile as slim as possible.

• Compatibility Tip: Most holsters molded for a Glock 17 with a TLR-1 will also perfectly fit the Glock 22 and 31, as their external slide and frame dimensions are identical.

Pro Tip: If you find your TLR-1 gets "carbon-caked" from the muzzle blast after a range session, a light coat of Chapstick or a dedicated lens protector on the glass before shooting makes it easy to wipe the soot off afterward.
