So back in WW2 when they would make any kind of whacky gun design, there were a number of silenced guns that were actually pretty good, even by today's standards. The Sleeve Gun was basically like a silenced Liberator pistol: You'd get one, fire your one shot into someone with a better gun, and take their better gun. Since it was silenced, a person could use it as an assassin's gun, but actual assassins were more likely given actual semiautomatics or rifles with silencers. The Sleeve Gun is built on another gun with an integral silencer, called the Welrod. The Welrod used a magazine (clip, if you must) as its grip, and reloaded by bolt action. The Sleeve Gun took off the multi-shot magazine, and moved the trigger to the front, flashlight-style. It had a lanyard hole at the end, so a person could thread a length of surgical tubing into it, to make it slide back up into the sleeve after using it, and keep it from just falling on the floor when its user tried to draw it.

So you'd have this, loaded, up your coat sleeve on surgical tubing attached to your arm or shoulder, and when you were ready to kill someone, you could drop it down into your hand, shoot the person silently (from point blank range only, it had no sights), and either use it as a truncheon, or reload it VERY SLOWLY.

The original design was a pretty good design, but we think it could be improved by changing the .32 round to a .410 shotgun shell. Shotguns are rarely silenced because the use of a silencer spins the shot cup, causing a "donut" effect in shot distribution at a distance, making silenced shotguns only useful at close ranges. The sleevegun itself is only good at close ranges, so it really is a perfect fit. This, of course, will never happen, because nobody reads this site.

Because most of the images are Timelapse's, we're limiting our coverage of this gun to a couple technical drawings for now.
