About 90% of the time the G21SF rides in a Raven Concealment Phantom set up with IWB overhooks. For my body style this conceals well under even a simple dark t-shirt. Have also used an MTAC, CTAC, Infidel with good success. Just ordered another RCS light compatible Phantom to see how that works. I am considering a Galco Jackass or Andrews Leather Monarch shoulder rig to get the weight off the hips. Not sure though as shoulder rigs and indont tend to mix well. Wanna kill these ads?
