My alternating 2 carry guns will be a Rossi .357, 2" snub nose revolver and a Taurus PT111 Millennium Pro 9mm. An H.K.S. speedloader for the revolver and a spare 12 round mag for the Mil Pro will provide some "extra" if needed. Each loaded gun and spare ammo fit very well and ride comfortably in a fanny pack. Any pro or con opinions on the use of a fanny pack would be appreciated.
