What about for running a pistol holster? My belt on my pack prevents my hip holster and while I can certainly keep it on my pack belt, I'd rather have it on my person for a number of reasons.
I've got the same set up and was thinking the same thing.I've used a paddle holster for the past several years. With my daypack, the thin belt goes behind my G20 when it's on my hip. With my Stone Glacier and the thick padded waist belt, I just put the holster on the waist belt. If I were to take the pack off for whatever reason, the holster can easily be moved back to my hip.
