wow, thanks for all the insight...for clarification, in the state of MO, you can open carry, or with a permit, concealed...i have had the CCW for over 2 years now, but here's the catch -- if you conceal, it must be TOTALLY concealed, if you OC, it must be visible and noticeable publicly from 2 separate vantage points...so i can't carry concealed, and then if my shirt untucks and shows the weapon, claim OC laws...i dress casual, but am still in the clean-shaven, high/tight mode from Marines, and the few occasions that i have chosen to OC, the comments i've overheard are that they suspect i'm off-duty cop (um, most off duty cops conceal i think, but idk)...i DON'T do this everyday, and the idea for a group gun-a-thon sounds dumb as hell, i was just curious how many of you HAD done it, and if you felt it LIMITED your vulnerability or ADDED to it...from the input i've read in all of your great responses, i see a trend towards concealment over OC...my only "devil's advocate" argument over that would be my response time concealed vs. OC...open, i can put 2 shots on target in less than 3 seconds, very surely (helps a bit with the weapon i'm using)...concealed, i have at least double that...
