Gamo MP9 Semi-Automatic Blowback Pistol .177 Caliber
"The Gamo MP-9 is a real replica from the B&T MP-9 9mm submachine weapon. MP-9 is a light weight, small size, folding stock airgun. The realistic tactical design from B&T, velocity of up to 450 fps, dual technology (pellet and metal BB's) and semi-auto mechanism, make this airgun and excellent choice. Only standard-skirt pellets should be used with the MP9 pistol. To avoid damaging your magazine, never use long-skirt pellets, such as: Red Fire, Blue Flame, Glow Fire, PBA Bullet, Magnum, Master Point, Armor, Lethal, Rocket or TS-10."
