The STP45 is part of G&G’s modern gas blowback pistol lineup, designed to provide efficient operation and convenient field adjustability in a lightweight platform. The pistol uses a polymer slide combined with a CNC-machined metal middle frame, reducing slide mass while maintaining structural strength and durability.
This construction helps improve gas efficiency and promotes smooth blowback cycling, delivering responsive recoil while keeping the pistol comfortable to handle during extended gameplay.
One of the defining features of the STP45 is its integrated adjustment system, which allows users to tune both hop-up and trigger pull directly on the field. The pistol includes a dedicated adjustment tool stored within the slide beneath the barrel, ensuring the tool is always available when needed.
By inserting the tool through two access ports within the trigger guard, players can quickly adjust hop-up and trigger settings without removing the slide or using additional equipment. This system allows fast tuning depending on BB weight or personal trigger preference.
The pistol utilises a 104 mm inner barrel, providing stable shot performance within a compact sidearm format. The adjustable hop-up system allows precise tuning of BB trajectory to maintain consistent accuracy.
Externally, the pistol features a full-size ergonomic grip frame with textured surfaces that provide secure handling during rapid firing. The frame also incorporates an accessory rail under the barrel, allowing users to mount tactical lights or lasers.
With an overall length of 203 mm and a weight of 840 g, the STP45 offers a balanced and lightweight shooting platform. The pistol is supplied with a 30-round gas magazine, providing dependable capacity for extended sidearm engagements.
