Learning to draw, increasing your muscle memory and adjusting your mindset are three important aspects of concealed carry.
There are many ways to draw from different concealment positions, and learning and practicing the best ways for you are crucial. You never want to be in a situation where you need to get to your firearm quickly, but you find yourself fumbling with your jacket or shirt. Practicing in your home (with an unloaded firearm) and practicing at the range on a regular basis are important as well.
When I first put my firearm on in the morning, I take a few minutes to practice drawing in front of the mirror with what I’m wearing that day. A longer shirt than you’re used to wearing can make a big difference when drawing. Your hand needs to go down just a little further to get a hold of the bottom of your shirt. These things need to be taken into consideration at all times.
