ST Action Pro - 9mm Yellow Action Trainer Dummy Round - 5 Rounds (Original Version)

Great teaching aid. Made well. No problems. Would purchase again.

This is my 3rd attempted to get fake bullets to practice on my 9mm. All the others got stoke when you tried to remove them, this one doesn't. So get yours NOW.

These work perfectly and fit any 9mm firearm for safe practice. They function perfectly, not sticking or hanging up. Very durable and cheaper than most. Very handy for private practice or being an instructor.

God for practicing drills and malfunction training. Happy with these no frills practice rounds.

This is a teaching tool. It will help you to learn and accept that even the best ammunition misfires occasionally. Your teacher will load magazines with one or two of these in each magazine so that, when the gun fails to fire, that you know what to do in order to clear it and continue to fire.

Casings are perfect. Plastic is not too spongy but good quality so it doesn't run off in the magazine or when chambering. Well made and great price

Does the job, works great on my Taurus G3

First off want to say these do work... but they do not even come close to simulating the accurate weight of a real round so makes them really next to useless for anything but trigger practice. You also only get 5, which means to get enough for a full magazine so you can practice loading, unloading et cetera you're gonna need to buy 3 sets which, based on what I paid for mine, is more expensive than a box of real 9mm. Also they do not like to chamber, they jam frequently which does, to be fair, have training advantages. Basically what I'm saying is I wouldn't buy these again but I am glad I have a set of them at least because they ARE valid training tools... you just can't rely on them to be accurate tools. The best thing you can do with them is to mix a couple in with live ammo to see if you're flinching or anticipating when firing live. Other than that... I don't think they serve that much of a purpose since dry firing a modern handgun is pretty much safe to do anyway due to how they're engineered without risking damage to your firing pin.One other thing I suppose these could be good for is learning how rounds interact with your handgun and being able to SAFELY see how everything works, because knowing how things work is very useful.
