Evolution Airsoft show their airsoft gas blowback gun series in this video... "When we decided to start making handguns, here at Evolution International we started from a blank sheet. We reconsidered the standard manufacturing procedures used by the most in the Airsoft Industry and we adopted a unique manufacturing protocol inspired by the firearms industry. The result is a line of handguns with excellent finish, smooth action, accurate shooting and with a hard kick. Our guns are designed in Italy, hand-fitted by our technicians to minimize the tolerances, tested one by one in our shooting range and packed in an impact-proof Made in Italy Pistol Case."
