The file 'Dummy 9mm No Slide Lock 3D Printer Model' is (STL) file type, size is 15.2KB.
A dummy 9mm round for practicing dry fire, but it's designed not to get stripped by the slide. So you can put one in a magazine and you won't have to deal with the slide locking back due to an empty magazine. Great training aid!
Tested with Glock magazines.
