@SouthNarc: Lead us not into temptation!
It's not like I don't have a couple of closets full of day packs, fanny packs (and let's not even try counting holsters). I have the GR1 21L, and like it in general. But for my typical uses - - - to and from car & work, rarely long distance travel, etc - - - a sling that carries just the Rattler, an extra mag or two, light, first aid, etc., is "feeling" more suitable. And certainly one that, color-wise, leans to the "happy" side as opposed to the "tactical" side would be better.
Resist . . . resist . . .
