Ok, so I probably have about all I need for the clinic. Mag pouches and dump bag on a molle tac vest. My IDPA gear: pistol + holster and mag pouches on my belt. A Norico M4 with a sling, some accessories, iron sights and 3.4× optics. And the norc has a Neit arms 4 port comp I got ages ago. I've only used it a few times, since installing it, its quite loud.
I see in the photos above, it looks like we will do drills standing in a line, so I'm thinking I need to change the comp, or do lots of the attendees have these?
Eventually I plan to replace it with one of those fire breathing piggy type comps, this could be the impetus to get moving on that.
