Nut Slapper

The Nut Slapper is a PDW weapon currently produced and sold by SLAP Weapon Manufacturing. It is currently in service with 15 different PMCs and 2 third world countries.

Origin
The Nut Slapper was originally envisioned by an anonymous individual in 1901 as a variant to Mauser's C96. The idea of the gun was to better subdue male adversaries on the battlefield. This concept saw interest from Mauser and in 1902 they began to develop the idea. It then failed dramatically and the blueprints were sold off to some random shmuck. This random shmuck then sold it to another random shmuck, and the cycle repeated until it found itself in the hands of the Patriot, who wasted no time manufacturing the thing and selling it like hot cakes. You can buy the original prototype from Rock Island Auction.

Functionality
The idea of the Nut Slapper is to cause excruciating and ceaseless pain to the testicles of both the target and the shooter. It achieves this with a voodoo Tac Sac hanging beneath the weapon's stock which flips and flops as the gun fires at 6000 RPM. The feed mechanism of the Nut Slapper is shaped like an infinity symbol (∞), allowing the magazine to hold infinite rounds of the proprietary 9x19mm "Big Slappy" ammunition, made to have stupid amounts of recoil in a small package.
