I am a huge fan of the G code RTI system. It is the ticket if having your sidearm on you is needed at all times or you like options. It provides flexibility to move from your pack's hipbelt when hiking, straight over to your pant's waist belt if you drop your pack for any reason at all (think in and out of vehicles/atvs, stalking, etc).
All can be done with a single kydex holster (nunerous quality companies have adopted it as a viable mounting option) and two separate attachments. I have a number of holsters for different pistols with the system and can strap any to my kifaru in seconds which has a permanent mounting plate.
Have been tempted to go with the JC style as they look awesome, but the RTI fills the bill when running minimal and affixed only to the pack for a trip.
