Re: What do you carry and why ?
The keys to alternating carry weapons are:
Train with each one to the same standards. (The more challenge, the better.)
Practice presenting with each one to the same standard.
Mental rehearsal. When you strap on, put your brain in the right gear. Reach under your shirt a few times and achieve a grip; make sure your brain knows what weapon it will be fighting with this time. Rehearse the safety, sights, trigger etc etc. (Combat is won or lost in the brain first, right?)
Never say die!
