NH Shooter - Do you thread the instructor belt through loop on you pants, adding stuff as you go, or do you wear the rig over another belt?
ETA: As a young cop I had the belt loops on my duty trousers modified to tak a Ranger style duty belt. It was a PITA to get dressed, but at that point being fresh out of the Marines I wanted to look sharp. The only disadvantage I say, other than the time to get dressed, was striping off the gear in a hurry once I got the holster locked down. Since we didn't have much opportunity for water rescues, I figured I'd roll with the ranger belt. Lasted about a year before I went back to a more traditional duty belt.
Those Safariland two-shell holders have been the go to for LE carry over 20 years.
