Glock G23 Gen4 .40 S&W Compact with Trijicon Night Sights, Threaded & Standard Barrels
This Austrian-made Glock G23 Gen4 pairs the proven law-enforcement pedigree of the compact .40 S&W platform with practical upgrades that add value for both carry and range use. Factory-installed Trijicon night sights give clear, low-light aiming, while two Lone Wolf drop-in barrels—one threaded, one standard—let you choose between suppressed or competition setups. A custom slide backplate and the complete Gen4 feature set round out a pistol that is ready to adapt to multiple roles.

What’s Included

The Gen4 G23 uses Glock’s dual-captive recoil-spring assembly to soften recoil and extend service life, especially helpful with .40 S&W pressures. Aggressive RTF3 grip texturing and interchangeable backstraps let you secure and size the grip to your hand, while the reversible magazine catch supports left- or right-handed shooters.
Trijicon tritium sights top the Tenifer-treated slide, combining corrosion resistance with a bright yellow-outline front blade for fast sight acquisition day or night. The installed aftermarket slide backplate adds a personalized touch; the factory plate is included if you prefer the stock look.
Two Lone Wolf stainless steel barrels expand the pistol’s versatility. The threaded model is ready for a suppressor or compensator, protected by a knurled thread cap. The non-threaded barrel offers a drop-in option for training or match use, and both maintain Glock’s reliable lock-up.
Austrian proof and inspection marks verify its origin, and the serial prefix “UFF” aligns with late-production Gen4 runs. With a 13+1 capacity, Safe-Action system, and integral accessory rail, this compact .40 S&W remains a dependable choice for defense or duty while offering ready-to-go upgrades out of the box.
