GAMO P-900 IGT Air Pistol

Gamo P-900 IGT air pistol IGT gas piston (IGT=Inert Gas Technology) Breakbarrel Single-shot 30 lbs. cocking effort Fixed fiber optic front sight Windage-adjustable rear sight Rifled steel barrel Ergonomic design Textured, rubberized ambidextrous grip Manual safety 2-stage non-adjustable Smooth Action Trigger (SAT) Here are the benefits of the IGT over a metal mainspring: Smoother cocking Smoother shooting No spring torque No spring fatigue, even if you leave it cocked for hours Functions perfectly in cold weather Lasts longer than a metal spring Gamo USA states that this gun gets 400 fps (and Gamo traditionally provides velocity figures for alloy pellets, not lead pellets). However, airgun writer Tom Gaylord tested the P-900 with Gamo Raptor PBA pellets (5.4 grains) and got a whopping 508 fps! For a 10-shot string, he got an average of 490 fps. As a result, our velocity figure for this gun does not agree with Gamo's claim.
