Galleon"Edge"

This work uses an airsoft Colt Python as the base and is in the image of a futuristic custom gun. This weapon is Galleon “Edge” and is exclusively used in human mechanization battle games. It uses .357 Magnum ammunition. The main ultra-hard blade can easily cut through light armor, so it is used in mid to short range combat against mechanized enemies.
