Re: Number Your Magazines
Good stuff and great ideas for all.
I have done as Marlin. I have marked mine with an X on the side and keep them for my practice mags. I want to have failures during practice to cause me to have go through the failure drills. But once marked they are never reintroduced into my "ready" bag.
The good thing about these failed mags is you never know when or if they will fail so the drills are actual/real when it happens.
Stay safe, always.
