Gamo P-900 IGT Air Pistol – 4.5mm

The Gamo P-900 IGT is a 4.5 mm single-shot break-barrel air pistol that replaces a conventional metal mainspring with Gamo’s Inert Gas Technology gas ram. The self-contained system needs no CO2 cartridge and is designed to reduce spring vibration during the firing cycle.

Verified specifications

Who this model suits

Choose the P-900 IGT when a self-contained break-barrel format is preferred but a gas ram is more attractive than the conventional spring used in the standard P-900. Each shot still requires a full cocking and loading cycle.

Operation and compatibility

• Use compatible 4.5 mm pellets only.
• No CO2 cartridge is required; the barrel is cocked once for each shot.
• Follow the manual throughout the break-barrel loading cycle and keep a secure grip.
