I've been using the Eberlestock Bando Bag for a few weeks now as an occasional carry option with a Sig P239 or Glock 19. Fit is just about right for both, but not much extra room for anything bigger. I prefer carrying the P239, since I feel comfortable sans holster with the DA trigger. Spare mag, wallet, badge, keys. My issue is that I ordered the multi-cam pack, which stands out a little. I just ordered the blue/gray version so maybe a little lower profile. It's got some organization dividers inside, which are nice to keep things in place and from just bumping around into each other. My issue always has been trying to carry too much and taking a minimalist setup and making it into a war-rig. The Bando Bag helps me to keep that to a minimum.
