The P320-M18 is as close to the original as possible in terms of weight, balance and handling. The high-end airsoft pistol SIG Sauer ProForce M18 GBB was developed for professional training by the army and authorities and is a realistic replica of the 9mm pistol in all diameters. The globally valued SIG standards for precision, accuracy and reliability were the requirement. The ProForce M18 is made of high-quality polymer and a metal slide and has a built-in 22 mm Picatinny rail for quick and easy attachment of accessories, 3-point sights and an adjustable SPIN-UP system for an optimized hit pattern. Like its real counterpart, it is optic-ready, has a removable rear sight plate (suitable for the Sig Air Reflex target) and is easy to dismantle. The strong blow-back system provides a realistic shooting experience. The included short gas magazine holds 21 rounds of 6mm BBs, but the pistol is also compatible with the optionally available M17 CO2 magazines.
