HSGI Pistol TACO® LT Pouch - MOLLE
This versatile pouch will hold almost any pistol magazine, mag light, multitool or knife in a package 30% lighter than the original!
Molle: HSGI® clips for attachment to PALS.
Belt: Includes velcro wraps to attach to up to 2" belt
Dimensions: 1.2" x 1.75" x 4.0"
For double stack magazines this seems to work well, I'm not sure how good the retention would be if you were using single stack magazines.
