Things I liked: Very compact, Well made, and the "Polymer" plastic used is solid, Unlike some manufacturers who tend to skimp on this part. Although stated as being "Blowback", I think the True definition of "Blowback" should be a little more Informative, because the Gamo MP9 is certainly not the same as the Gamo P25, or PT85 in that term, With an added Leapers UTG CQB R/G Dot sight(3.9"), It's surprisingly accurate to around 25 ft, The first 8 rounds, come out "Screaming", but steadily diminish, and by the end of the 2nd mag, You'll be changing your Co2 cart.

Things I would have changed: Fiber Optic sights, Adjustable for elevation in the least, Package it with 2 magazines,, Also make it a True "Blowback" a/g, as well as using 2 Co2 carts, much like Umarex/Winchester.

What others should know: If you bought this a/g, and would like to get extra magazines, The magazines used in thw Winchester M14/M4 are a direct fit, and function Flawlessly

Things I liked: Feels a bit light, but it has a good handling feel! Well design very similar to real!

Things I would have changed: I would have made it full auto, for semi is not that fun but for that it will need a higher capacity perhaps a 30 round pellet mag!

What others should know: It is NOT blowback, not even an itty bitty tiny bit, however it is a nice gun to have in your collection! My daughter loves it!

  • Jim R from USA asked:

    What exactly does this "blow back"? I don't see a slide or trigger? Half the reviews say it is blow back, the other half say it is not? Any definitive answers?

    • Tyler from USA:

      The blow back comes from the ejection port. The slide actual blows back with each shot. It is not traditional blow back like most CO2 pistol shooters are familiar with.

  • Andrew from Canada asked:

    Are Spare Magazines being sold for this model?, or will it take Gamo PT-85/P-25 model magazines?, Thank's, Andy.

    • Andrew from Canada:

      The magazines from the Winchester M14/M4 are a perfect fit, and function Flawlessly.Also, Crosman Premier "SuperPoints" give nice tight groupings upwards of 20 Meters

    • Jerry from USA:

      You would need to contact Gamo, the PT 85 mags will not fit
