Summary

Allows you to hold a flashlight in your strong hand while shooting a pistol without materially changing your grip. The palm plate is at a 10 degree angle.

I have finally settled on a form factor for this design, but it is easy to replicate/adjust. This version works with a flashlight with 23mm body. Print the piece and attach the light with zip ties. When you need the light, grip your gun as you would normally and slip the flat piece between your palm and the pistol grip. It's not perfect, but it allows you to use almost any regular flashlight with your pistol. See the pics.

It's a simple principle - adapt to your needs. If it's stupid and it works, it ain't stupid :-)

Choose the model based on your strong hand (Right or Left) and print with high infill for sturdiness
