BarrelBlok transforms any self-loading 9mm, .40, or .45 handgun into a completely safe, realistic, fully-functional training tool. The cartridge-specific insert blocks the chamber and runs the length of the barrel, immediately showing the pistol is clear. The extractor can not remove BarrelBlok and normal function is unhindered.
MagBlok is a cartridge-shaped device inserted into the top of an empty magazine. This prevents the magazine follower from engaging the slide stop, and a ramp channel on the top of allows for the full back-and-forth movement of the slide.
With a BarrelBlok and MagBlok in place, dry practice and class demonstrations can be conducted with no chance of negligent discharge.
