WE HK3P PX4 Bulldog GBB Pistol – Gas Blowback Black
WE HK3P PX4 Bulldog GBB pistol delivers reliable gas blowback performance in a compact, lightweight package. Approx. 300fps with 0.20g BBs, fitted 20mm Picatinny rail, and mixed-material construction for durability. Semi-automatic only.
The WE HK3P PX4 Bulldog is a practical gas blowback sidearm purpose-built for skirmishers seeking a trustworthy secondary or primary pistol. Its compact 20.5cm length and 0.55kg weight make it ideal for CQB sites, woodland ops, and loadout versatility.
Key Features
- Gas blowback action – authentic slide cycling and tactile feedback
- Approx. 300fps (±10%) – consistent, site-friendly energy output with 0.20g BBs
- 20mm Picatinny rail – mount lights, lasers, or optics for enhanced target acquisition
- Compact 20.5cm platform – lightweight secondary or primary for tight quarters
- Mixed-material build – alloy slide and barrel for durability, polymer frame for ergonomics
- Easy hop-up adjustment – accessible when slide is removed for field tuning
Real-World Use Cases
The HK3P works well as a primary for CQB skirmishes where manoeuvrability trumps range, or as a reliable secondary for milsim loadouts. Its low capacity (approx. 22 rounds) encourages disciplined trigger control and pairs well with a primary rifle and spare gas magazines.

UK Legal & Site Notes
This pistol is a fully functional airsoft replica. UK players must be UKARA-registered or play at an insured airsoft site. Always use lower-velocity pistol rounds (0.25g–0.30g) on shorter ranges to respect engagement distances. Green Gas performance drops in cold weather; propane adaptors are available for winter use.
