For a variety of reasons I switched to a G17 plus two spare magazines as my EDC weapon but was never really happy with carrying it concealed at belt level. I was less than impressed with the shoulder rigs that I tested with it too. That has all changed with the arrival of my Alessi Bodyguard Rig. It took between eleven and twelve weeks to get here but the wait was worth it. I'm not sure if there is a truely comfortable shoulder rig but I will say that this Alessi product is the least uncomfortable rig I have ever worn. If you have a need for a shoulder holster, and the shekels, I strongly recommend this rig.
