I use this to display my pistols on a Wall Control metal pegboard. This hook fits the M&P 9mm, Glock 19x, CZ P10, Sig P229 and more. The ability of the hook to swing makes it adjust nicely to different size pistols. However if it doesn't fit your pistol, it can be adjusted to your specifications.

It is designed using FreeCAD 0.18 and the source file is included. Inside the source file is a spreadsheet where you can change the following values.

Peg Inside Height
Peg Board Thickness
