Lots of good advice on CC here. The one aspect of CC that I do not see addressed often online is 2nd magazine carry. In those instances where I have become aware of someone else attempting to CC it has usually been either a brief flash because their cover garment rode up or moved OR their method of magazine carry was as obvious as a brick. Too many of the magazine holsters are just plain obvious and do not conceal worth a dime. I use re-purposed multi-tool holsters for my magazine. When they are exposed people think knife/multi-tool and not GUN. Too many place too much emphasis on competition speed and access for their 2nd magazine. Honestly, the snap cover on my nylon multi-tool holsters work just fine, are plenty fast enough for real life, and I can carry them vertically or horizontally on my belt.
