Bought a new magazine holder for my G27 mag.
So far I am loving it. Messing around at Lowe's today and spotted it. Dropped my spare mag in and it was a perfect fit.
Say...I've got one of those. Cell phone holder? The velcro doesn't last very long on those IMO. Great idea though.
I use the same thing for my G26 mags on occasion. It's a great inexpensive holder. Just be sure to cover the cutout at the bottom, or you may end up with a bullet peeking out. Children seeing that find it highly interesting.
