You’ve seen it in movies such as:
And many more…
I should have known that people would build their own!
There is a tutorial on youtube. It definitely could have been more helpful with the plans, but if you are good with you are mechanically inclined I’m sure you would be able to figure it out.
There Doesn’t seem to be very many people on YouTube that built one, besides one Asian guy. His works and looks awesome though (see video below). Very Taxi-Driver-esque! He ever has the De Niro style jacket from Taxi Driver on.
I wouldn’t recommend trying to build one for anything other than pure entertainment and proof of concept. The fact that the gun is flying out of your sleeve means that if the trigger catches on something on the way out, the gun is going to fire. Use a toy gun. If you happen to not heed my warning and build one for a real gun, pleese do not conceal carry this way, because it is not safe for so many reasons.
I can see it now, you’re at a Starbucks about to hand the barista your Rewards Card and all of the sudden your Ruger LCP flys at light speed of of your sleeve. A dozens Starbucks patrons crap their pants, you make it on to National news, the Brady campaign uses you as an example, and you go to jail and pay a huge fine. It’s not worth it. Your Friends will be just as impressed if you use a toy gun, and don’t take it off your property.
