Fillamentum PLA and PET - for the spring
Print Mag_Left and Mag_Right at 0.3mm layer height if possible. If you print at 0.2mm, an extra layer will be added and it may not fit properly in the mag well since it will be slightly over sized. I was able to get consistent results at 0.3mm layer heights and saved some printing time!
SAND ALL CONTACT SURFACES!
If you want your Hand Cannon to function like shown in the video, you need to sand all high friction areas, including but not limited to the Latch, Launcher, Frame and Bolt. Use a doubling strategy from 100-200-400-800 grit sand paper for best results.
Watch the video first before starting assembly so you can familiarize yourself with the process and do it right the first time!

Hand Cannon Video
This real life prop replica has realistic blowback that allows it to chamber and eject empty cartridges. This video shows some of the build process that went into making the Hand Cannon come to life!
