[Taniokoba] GM-7.5 Colt Mk IV Series 70 Model Gun (Resale June 20, 2025)

Tanio Koba's GM-7 series is a cutting-edge model gun based on Tokyo Marui's 1911.

More than 50 years have passed since the world's first detonator blowback was developed during the old MGC era.

This is the culmination of the GM series, in which toy gun designer Taizo Kobayashi, Japan's first model gun developer, has poured all of his accumulated blowback model gun know-how into it over the years.

The patented ultimate open detonator system enables operation with a lightweight, inexpensive reinforced resin cartridge.

This gun was created not only as a model that is fun to look at and enjoy to touch, but also as a "toy gun" that allows you to experience the same movement and impact as the real thing.It is designed with the utmost importance to make the maintenance required by the use of gunpowder easy and to make it easy for anyone to operate safely and easily.

The exterior is based on the Tokyo Marui 1911, so you can use Marui accessory parts. The wide range of aftermarket parts available expands the possibilities for customization.

The grip can be fitted with a genuine 1911 grip. In addition, the old MGC GM magazine can also be used.

The GM-7 series comes standard with a faux wood plastic grip, but this model in particular uses a HW grip, which increases the weight and gives it a more textured feel.

Includes a 7-round steel magazine. Cartridges sold separately.
