Practice with the pistol that you carry. And I don’t mean just stand there and shoot. I mean practice the way you spend your day. For example, most of us spend a lot of time sitting down every day. Therefore you should practice drawing while sitting down. This can be done at home as part of your dry fire routine (and remember the safety rules apply to dry firing as well). Practice while sitting at a table, in an easy chair, in an office chair…anywhere you are liable to sit. Then on your next trip to the range do some shooting while you are seated…you will be surprised how well you do and will see your confidence increase. And remember, like your spare tire, you never know when you may need it!
