The file '9mm Double Feed Dummy Round V2 3D Printer Model' is (stl) file type, size is 36.6KB.
This is a double feed dummy round that act's as if you have two rounds trying to chamber. I work at a gun range and needed something to use that would act as a double feed without using live rounds. This is an easy file to print and I will be adding another file with multiples that will print at the same time. This is a work in progress as it works with the handguns I own so it might not work properly in yours. This dummy round should not chamber or feed into the barrel at all. It should hang up in the magazine and jam the slide keeping it from closing, You would then have to rack your slide to clear it and if that didn't work you would have to drop your mag clear your slide and reinsert a new mag. Please keep your feed back positive as this is my first try at designing something.
Updated: New File with new style. I'm hoping this works for more people. Not as brittle as the other one I made was. Let me know if this works better for. I have only tried it in my Springfields.
