G&G Armament Piranha MK I Gas Blowback Pistol

G&G Armament
  • Ceramics Whirl Valve
  • Extremely Consistent
  • Split Slide Design

One of the latest pistols designed and built in-house by G&G this pistol does not disappoint. Carrying on the success from the GTP 9 this pistol contains all the latest advances in Airsoft pistol design, with a uniquely designed hop-up system and ceramic whirl valve designed to improve efficiency, reduce cool down, and enhance your Airsoft experience.

Full description


The pistol is constructed from high quality materials, with a full alloy slide and polymer frame. The pistol is wobble free, with a solid design. The outer barrel is locked in place for maximum accuracy, with minimal slide and trigger wobble. The slide is extremely smooth, with one of the smoothest splitting movements seen on the market.

What makes this pistol stand out is its split slide design. Unlike traditional pistols only the rear half of the slide moves backwards, meaning less force is required to cycle the pistol due to the reduced weight of the moving parts. The reduced weight improves the gas efficiency of the pistol, and increases the cycle rate allowing you to fire faster.

The pistol features a highly advanced hop-up system, as part of G&G Armament's new Gas System it does not disappoint. The hop-up unit and inner barrel are all one drop in unit, which is adjusted by twisting the inner barrel to adjust the amount of applied hop. The hop features a positive click, and securely locks into place making the pistol highly accurate. The hop is adjusted from the front of the pistol down the barrel using the supplied 'rip round' hop-up adjustment tool, and can also be adjusted by removing the barrel and hop assembly from the replica once the slide and frame have been split.

If you're after efficiency you've come to the right place. G&G's new gas system improves the efficiency of this gas pistol hugely. Thanks to G&G's new Ceramics whirl valve less gas is wasted, and is more efficiently transferred to the BB, and due to the materials makes the pistol less prone to cool down meaning you can get in more quicker repeat shots for longer.

The front of the pistol features a lower pistol rail allowing the attachment of a wide variety of aftermarket torches and lasers, allowing you to customise the pistol to truly make it your own. If you want to attach a suppressor or tracer unit this is possible thanks to the female threaded outer barrel, and with the use of an adaptor allows you to attach a wide array of aftermarket suppressors. Because the barrel is locked in place and not free floating you do not have to worry about cycling, allowing you to attach heavier suppressors and standard tracer units.

The pistol comes supplied with a carry case, magazine, and speed loader, giving you everything you need to get out and start playing: Just add BB's.

This pistol is the perfect addition to any Airsoft skirmishers arsenal, with optimal performance, with plenty of options for customisation, this pistol is a welcome addition to any collection.

Special Instructions

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.
