Understand something, there are various ways in which you can Extract and Draw a pistol. I would urge to consider practicing as many different options as possible when it comes to Extracting and Drawing a pistol. Also I would like for you to remember to keep in mind the following three things when carrying a pistol for Personal Protection:
Your geographical location will a play part in how you carry a pistol. To be more specific, the weather in your geographical location will more than likely dictate the way you carry your pistol.
The Law is of the utmost importance when it comes to how and more importantly where you can carry your pistol. In some states you can carry almost anywhere then there are some states where you are limited in where and what you can carry. In addition, keep in mind that they is a difference in the Federal, State and Local Laws. When carrying a pistol or any kind of weapon please make sure that you are in compliance.
Lastly, know the limits of your skill set. If you know you haven't practiced Extracting and Drawing the pistol in a certain way, do not be overconfident thinking you can Extract and Draw in that fashion when the time comes (shooting engagement).
All of this you already know. So get to it.
