Yet another challenge from TheDunkis Answered
Here's a cool idea I had for awhile. It doesn't seem too practical but still pretty cool if you can pull it off. True Slide action. Basically it's the same as true bolt action in how it works. Make a handle loading pistol where the slide pushes a round from the loading chamber into the firing chamber for more power. It actually shouldn't be that hard. The most difficult part will probably be the trigger. To make it more of a challenge, try making it as compact as possible like a real pistol.
I might actually be able to build and review the winner's this time. I'll give you a basic image to give you an idea of what I'm looking for...but mostly just so I can get through the filter faster.
