Esstac double pistol mag pouch for Glock
I like the mag pouch and the kydex retention. They hold the mags pretty much perfectly while being minimalist. I have the pouch on a Gray Ghost Gear UGF belt which I use as part of my overall kit in the military. They didn't have a multicam option when I ordered but I do recommend them. I would get the solid malice clips vs the lightweight flexible option. I feel like they are more secure and rigid.
Haley Strategic flatpack ridgid insert Molle Panel
I purchased the panel for my Haley Strategic flatpack and have found it well worth the money. The fit and finish is excellent and it has provided that positive contact point with rigidity lacking in the main compartment of the pack. I have a Glock G23, tactical tailor stealth admin pouch, CAT combat application tourniquet in a MIL-Spec Monkey pouch and an ESSTAC double mag pouch. I really like the ability to grab a preloaded panel, throw it in the pack and be out. I have since bought another one for the flatpack and one for a 5.11 Rush 12 daypack. Your buddies will be envious as well; expect lots of questions like where did that come from.
