Very intrusive modifications for the Airsoft Desert Eagle CM.121 Yes the images differ, emboss or extrude cut your own propaganda. I recommend fusion 360 or 3D builder.
The Why- My hands are too small for the Desert Eagle, so I made a grip to replace it. Mag bottoms to fit with the grip, grip nuts to add detail, a mag release for better reloads (PETG is too weak to it doesn't work well), and a muzzle device that fits the outside of the internal barrel and the inside of the upper for accuracy.
The How- Remove the existing grip covers, cut down the front portion of the grip close to be flush with the mag, cut and sand until the new grip covers fit, attach the new grip covers and plastic weld them together and fill in the gaps, lastly sand until its comfortable. Replace the mag bottoms by unscrewing the bottom two screws on the magazine, you should be able to figure it out. For the muzzle device, shove it on don't break anything.
The results- 8/10 poor fitment, lots of work, solves the problem, truer irons, looks better.
