A channel called "hyper" does (or did) a series of funny/ridiculous gun reload animations that inspired this animation here. This one was based off of his video "a really big glock", as you can probably see. Check out hyper's channel here https://www.youtube.com/channel/UCSezUnbvCLYBXuUlPcXU_QQ and the original "a really big glock" video here https://www.youtube.com/watch?v=g8WXWL_eZH0 I hope you enjoyed this animation, thanks for watching!
