This is a Pistol Display for a Shadow Systems DR920P. Using it for a cool display in my office while not in use. Would also work for a Glock.
I have two stands, one with a cut-out so you can slide the label in and one without a cut-out so you have to make a stand. This is the one I am displaying. I thought of making the cut out after I printed this and didn't want to waste the filament in reprinting it.
