Submission for today, a Futuristic Disintegration Pistol/PDW.
The gun runs on a smaller version of the batteries present in my Particle Beam rifles. Its standard mode is to fire a beam that disintegrates any matter on a molecular level, melting a brick of steel in about a minute and a soft human being in about 5 seconds.
The gun uses a futuristic fingerprint recognition safety which is programmed specificly for its unique user. Only that user's fingerprint can unlock and de-safe the gun.
Made in PMG .6
