2025.12.21 Update: Added different scaled versions of pins, for printing when the assembly is too loose or too tight

2025.09.21, the main improvement addresses the issue of bullets falling out when shaking the barrel after loading now after loading, shaking the barrel (you need to be quick, as the retention force is quite strong) allows you to close it without needing assistance from the other hand, making the action cooler The principle is moving the pivot point backward so that when shaking the barrel, the bullet's center of gravity remains inside the chamber Additionally, the diameter of the rifled barrel has been increased to reduce the bullet head hitting the rifled barrel and decelerating during firing

2025.09.09, no update, just uploaded the source files, gun enthusiasts are welcome to improve it ^_^

 

Caution! Caution! Caution!

The model poses certain dangers when loading the bullet and after the bullet is loaded, do not point it at people, animals, or other fragile items (such as computer screens, televisions), to prevent accidental discharge causing injury or property damage If improper use results in damage or loss, you are solely responsible for the consequences, and I bear no liability
