No band on defense mags. Band on greentips is where the lower part of the hand grips (pinky/ring finger) the mag for reloads and band on fmj mags index finger and thumb. Very tactile. Bands are really tight and I know they won’t move.

Yeah can’t complain about their AICS pattern magazines. Absolutely amazing for the price and function.

Makes sense, probably would do a band and no band setup if it was same caliber two options but I have a training prejudice to not look at anything but the target/threat area while reloading that tends to carry over in annoying ways.

I use the bands to differentiate my frangible home defense rounds and either greentips or fmj training ammo.

For the moment stuck with Magpul 10 rounders and mostly in AICS pattern but the rubber band idea is certainly workable/cheaper. I just know the kind of stupidity people can get up to with almost compatible gear.

The mags are $20 if you can find them in stock.

I use colored rubber bands about a half inch wide that are a tight fit on p-mags. Also Magpul has a see thru mag just not in any fancy colors.

On the other hand, P-Mags are so dead-nuts reliable and cheap, why change?
