After reading all the replies, I would like to say that I have carried a S&W, Sig, and a Beretta a few times "Mex" to go check the mailbox, or to jump in the truck to run to a drivethru to get a pizza, etc. I do not suggest "Mexican" carry or going without a holster while on foot, due to the chance of much physical movement could speed up the loss of the pistol being concealed/carried. The pistol is going to be there, so go ahead and put it in a holster, that is just smarter. After being a full time cop for 18 years still on the job you will see all kinds of holsters, and a decent belt holster will go a long ways to keeping your sidearm safe and handy just in case you need it...
