Good product! - FAB Defense Dummy Practice Ammo, Package of 10

Good Product!
Feeds and Ejects Low Price. Great for practicing fault clearance. Also, for checking trigger in operational condition on a Glock style action. The trigger does change a little when the round presses up on the slide.
I used to make dummy rounds by reloading without powder or primer. Then painting the base of the case red. But those only last so long before the bullet loosens up. The only problems I foresee, is the possibility that the plastic rim will probably get damaged after some use. And, the weight does not simulate a real round. But this is a must have for tinkerers & trainers.
