This is a simple pistol holder.
I tested it with a Tokyo Marui Glock, a CZ P09 from ASG, a ICS BLE Alpha and a HK 45 Tokyo Marui.
Do not use it with a High capa. I'll post another version later.
Do not hesitate to list other compatible airsoft guns in the comments.
I added the Fusion 360 file. Be creative.
