Moon Clip Checking
At home or at the range you can now safely check that a loaded moon clip will function properly without loading it into a cylinder. These checkers duplicate the dimensions of a revolver's cylinder. So after loading up the moon clips just test that they will go into and fall out of the checker. You will then have the confidence that the loaded moon clip will function when you're at the line.
This is the checker for the 6 shot 45 ACP revolver. Used to check the industry standard full moon clips for the Model 1917 revolver from both Colt and S&W. Also S&W revolver models 22, 25, 26, 625, 325 and the Governor.
