I typically do not run Molle belts specifically, but mine is compatible for Molle sizing. I use a hybrid system of Blade Tech training belts, which is comprised of a inner belt that threads thru pants with Velcro facing out. Then you have an outer belt that is configured to whatever that events needs are. You simply line up outer belt to witness point on inner belt and wrap it around. The Velcro is a full 360 degrees. And make no mistake it is stuck in place! You need to stop for lunch, take a break go to the bathroom or whatever you simply peel off the outer belt. It makes life so much better. Holsters for the most part I run Black Scorpion, it is compatible to the Blade tech system. The majority of vendors are now making their equipment compatible to Blade Tech system. I would not go so far as to say it is a industry standard but it has a lot of benefits and is super compatible, Molle included. The only downside is the miserable Chicago screw that is utilized. But a bit of lock tight solves that, and frankly regardless of what system you use inevitably you will be dealing with a Chicago fastener at some point.
