Go lite! Everyone but the instructors,showed up in various vest, chest and LBE/MOLLE tier two type(belt suspender or vest with pouches Worn over pants and /gun) gear with 6-10 magazines.
Instructors carried 1 or two spare mags for their ARs
Many of the guys had tier two mounted holsters and wear unarmed with their gear off.
By the third day most have switched to belt carry for handgun and removed mag pouches.
By lunch the first day I had 2 single AR mag pouches. with a mag in the gun and pouch on the stock I had PLENTY. I will egt a couple more Surefire 60 rounders and the one I had worked great. P mags with windows are pretty darn handy and robust.
Guys with 5-80 pistol mags are reluctant to speed reload, letting their expensive mag hit the dirt.
The middle of the road, price wise worked better than some of the high end guns FN SCAR and HK both had issues My Rock River and other Colt DPMS LMT CMMG etc guns worked great Both Ruger SR15s needed copious amounts of oil on the bolt carrier to work.
Oily dirty guns will run dry guns will not.
more to come...
