Wherever you carry your self defense weapon practice getting to it. A waistband carry is hard to get to when you are seated or even when you crouch behind cover. A boot holster is a backup weapon. there is no way to get to that gun without alerting everyone in the area that you are doing something strange. Depending on the gun and holster it can be very difficult to conceal. I finally got to the point that the only two carry positions that I can use quickly and easily conceal are a shoulder holster and a cross draw otw holster. I should say that my everyday carry weapon is a 6 inch 357 or a Colt 45. If I had a semi-auto that I felt I could trust my life to I could easily carry it in either position. Neither of these holsters are allowed in the personal training camps because the gun, when drawn, is facing more than 45 degrees to the side. The shoulder rig has the gun pointing to the rear as it is drawn. So in professional training classes I use a pancake holster that rides high on my right side.
