A Russian blogger posted photos of a Glock replica he printed using a 3D printer. The internal parts are all modeled reasonably accurately and it functions like the “real steel” would.
If you printed this pistol using a 3D metal printer, and loaded it with real ammunition, you would probably end up with an expensive paperweight at best, or a hand grenade at worst. I would not be surprised if the designer had intentionally altered the dimensions to prevent a casual user from creating a functional firearm. The tolerances may be fine for ABS plastic, but are probably not good enough for rigid metal.
I am not 100% sure, but I think the printing files for this pistol can be downloaded here. If you print of a replica, send us an email with photos of it.Related
