Nope - don't have one
But I was thinking about getting one as "proof" of being a good guy for taking some Mag 40 classes. Taking a class from Massad Ayob is on one of those lists of things to do after the first time I heard him speak.
Until I get the training - I figure I just don't have all the information I need to make that sort of choice.
Is there any down side for getting one even if you don't end up ever concealed carrying? Not too worry about being on some sort of "list" - heck, ex military so I know I am on a few folks lists.
