WE GP1799 T5 Custom Airsoft Pistol — Black

The GP1799 T5 Custom is a GBB (gas blow-back) airsoft pistol by WE, an unofficial replica of the Glock 17 in a custom configuration. Aimed at dynamic airsoft shooters and milsim enthusiasts looking for a ready-to-run custom platform, it stands out from the base version through its more elaborate appearance and the realistic cycling provided by the gas blow-back system.

The GBB system runs on green gas (or CO2, depending on the variant) and moves the slide rearward with each shot, replicating the operating dynamics of the original. This produces a noticeable recoil and forces a mandatory magazine change when rounds run out — elements that make pistol-handling training significantly more realistic than an AEP system. The trade-off is the one typical of GBB platforms: performance varies with ambient temperature — gas delivers better output in warm conditions and can lose efficiency as temperatures drop — and gas consumption is higher than on electric platforms.

The T5 Custom designation indicates a configuration with aesthetic and functional differences compared to the standard variant. The platform remains compatible with magazines from the WE R17/GP1799 line and with most Glock-pattern aftermarket accessories available in the airsoft market, including grips, triggers, and slide components.

Key points

• Gas blow-back system with moving slide: each shot cycles the slide, making the firing sequence realistic and well suited to pistol-handling drills.
• T5 Custom configuration supplied ready to use out of the box, with no additional work needed for those who want a look that differs from the base version.
• Compatible with WE GP1799/R17 magazines and with the most common Glock-pattern aftermarket accessories in the airsoft market.
• Declared for airsoft use only: not suitable for use with live ammunition.
• Temperature-dependent performance: a factor to consider when choosing gas and managing the pistol in cold conditions.
