A fun plinker for casual backyard get togethers and competition among friends and family.

Most pistols these days are powered by CO2, so it's a breath of fresh air to see a gun that requires nothing but you and a tin of pellets to let the fun begin!

If you're planning to teach someone to shoot air pistols, this might be a good one since you can leave it cocked without worrying about weakening a coiled mainspring while you give them instruction.

Are you an airgun sleuth looking to pick up some free Bullseye Bucks?

  • 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.

Things I liked:

Looks and price

Things I would have changed:

Made mainly of plastic and possibly a .22

What others should know:

This is an air pistol for a beginner. It doesn't have a lot of power or good distance but is accurate out to about 20-25 ya yards. This is not a pistol to eliminate pests...even the smallest of ones. I purchased because of the brand name and price but to me it seems to be made very cheaply

  • Wayne from USA asked:

    I am trying to find the barrel length as well as the overall length of the pistol. Anyone know?

    • Edith from USA answered:

      It's 12.60" long and the barrel is 6.25" long.

  • John Emm from USA asked:

    Hey PA ... You say that the "Smooth Action Trigger (SAT)" is a "2-stage adjustable trigger" and one customer says there are no adjustments at all. You say that the rear sight is an "Adjustable fiber optic rear sight" and the photos that you provide pretty much say something else. Would you check this out please? By the way, what exactly is a "smooth action trigger"?

    • Edith from USA answered:

      Gamo's 2014 catalog shows the "Smooth Action Trigger" logo next to this pistol and states that it has fiber optic sights. Their website still says it has fiber optic sights (but they obviously changed their mind according to what I see in the pictures), but it says it's a two-stage trigger with an adjustable first stage. I'll change our description. (The SAT is a crisp, adjustable trigger that breaks like a glass rod -- it's a huge improvement over their previous trigger.) Thanks for bringing this to our attention!

  • Noah from USA asked:

    does anyone know how much foot pound of force this little sucker produces?

    • shaun from USA answered:

      I only chronod the cheap beeman hollow point and my cabin is at 5000 ft elevation and I get average 300fps at kids red ryder does about 280 safe ballpark lead pellet ft lbs is about 2 ft lbs at muzzle..the ft lbs will be more for the pistol due to heavier pellet but expect red ryder like fps...still very happy with pistol tho and as Tom and Edith mentioned his test with alloy ultralight pellets was fast but youll probably average between 300 to 400 fps max with lead pellets at lower an aside,,my prayers go out to Edith right now with medical situation.

    • oats from USA answered:

      3.1 foot pounds of muzzle energy.@ 508fps.

    • Edith from USA answered:

      It takes 30 lbs. of cocking effort. I can cock a P17, but I can't cock this gun -- at least not more than once! I can cock a rifle that takes 30 lbs. because of the extra leverage, but this pistol is hard to cock in my book.
