“The DryFireMag is the first of its kind that I’m aware of. I’ve always been huge on dry-fire…but it’s critical that it’s done correctly. To do this, one must be able to move the trigger finger back and forth in the exact same manner as when actually shootingmultiple shots in real live fire. The DryFireMag does just that…and the best part is it’s simply a magazine that easily pops in and out of the gun. Thanks.
