Full description


Unlike other Pistols, the slide is constructed from Polymer due to Japanese Laws, however the upside to this is that it gives the pistol better gas efficiency and accuracy. The top of the pistol features a white dot highlighted front sight and an adjustable rear Ironsight, allowing you to zero the pistol into whatever range you require. The Grip of the pistol features a textured pattern, giving you a better hold on the pistol, as well as a Beavertail safety, only allowing the gun to fire when properly held. The slide features an Ambidextrous Hammer Lock, ensuring that the pistol cannot be fire when the safety is on and Placed in a Holster. The pistol comes with a 31 round magazine, which is gas filled from the bottom of the slide. The package comes with a lower rail for the pistol, which can be attached with modifications to the pistol (See Special Instructions) allowing the use of Torches and Lasers. The pistol is Branded with TM Trademarks and naming, giving the pistol a great final finish. This pistol is a perfect purchase for any Airsoft Skirmisher who wants one of the best performing pistols in the market, and for those who will not settle for second best.

Special Instructions:

The lower frame of the pistol features grooves which need to be punched out in order to fit the lower rail. These holes can be accessed by removing the top slide.

Please note that once the holes are made the pistol is classed as modified and cannot be returned.
