I wanted a way to secure my CCW in the car and found that most of the time when I was on long trips I just set it in the cup holder. I created this insert to fit snugly in the cup holder of my Chevy Uplander. When the muzzle is inserted it is forced forward causing the front sight to catch in a recess that helps to lock it into place. This is specifically for my Sig P229 but also fits a friends 1911 and Skyy 9mm (although not as securly due to the shape of the trigger guard.
I designed this in Tinkercad so there isn't any step file or any way to customize it outside of changing the scale.
I can't help but feel I need to make a note that says I'm not responsible for any accidents that are/could/might happen while using this. I have assessed my own situation and decided that the reward is greater than the risk and have put every effort into making this as safe as I can at this time.
