What can’t Gorilla tape do?
I love this stuff, and it works great for keeping my dummy rounds from flying out of my magazines and all over the garage during dryfire.
Some folks don’t drop magazines.
If that works for you, it’s the simplest solution. Start your drill without a magazine in the gun, push the magazine button, and then load a magazine into the gun. I tried this for a while, and I found that I started to get lazy about really pushing the magazine button in all the way, and it cause me some grief on match day.
Put a .40 dummy round in the top of your 9mm magazine, or a .45 dummy round in the top of your .40 magazine.
I tried this, and it works better than nothing, but I’d still lose my dummy rounds from time to time.
I’ve never lost a round, and it’s never come off. It’s stupid easy to replace, and it’s cheap. I love it.
