If you have more than one pistol how do you differentiate the mags?

Color Crayon.

Heres an idea.

Maybe crayon over the caliber markings on the magazine, then wipe off the excess. In (whatever color you choose) it'll say 9mm, .40 S&W etc... in bright colors.

As an example think of the Glock and USP slides, how people crayola over the markings.

Black Magic?I think that's the best combo of El Cids & Old Fuffs' ideas.

For what it's worth I think El Cids paint marker *might* last longer than a crayon.

'nother vote for ziplock bags, marked.
