re: the original question... yes, without a doubt. I have several weapons that I regularly carry and stay very proficient with, and my attire, destination, mood, and company do have a good bit of influence on what I carry.
re: concealed carry, does not always mean nobody knows it's there. Almost all of my friends carry, most of my co-workers and business associates carry, and the question of "what are you carrying today" followed by show and tell does occur on frequesnt occasion. Most frequently in the company of someone who is not carrying, but that we hope to bring in to the fold...
It's kind of neat watching the thoughts cross the face of someone that you have been doing business with for a few months realize, in a restaurant, at a table of eight, that they are the only person that is unarmed, and that everyone else has always carried at all times from the beginning of the project, but they had not known and hadn't considered the issue, and are now dying to ask.... what everyone has, and why, and what are the advantages and disadvantages, and recoil, and durability, and reliability, and carry method, and holster quality and range availability, and requirements of carry license, and "holy crap! That's huge! how did you conceal that!?" and "wow that's pretty, how long have you had that?" and "why a laser?" and hwo much woudl something like that cost me? and "why didn't someone tell me that this was okay?" .....
And yes, we wear our BBQ guns every Friday at the weekly dinner at my place. Guys, Gals, and most of the kids... (since they're all adults now anyways...)
