Do you carry your handgun while driving in your vehicle? If so, have you practiced drawing (presenting) your handgun from the driver’s seat? (If you haven’t you should!)
You can practice in the privacy of your driveway. Make sure the gun is unloaded…and then check again to make sure. Then practice drawing your handgun.
Practice with and without your seat belt as well as unbuckling your seat belt as part of your draw. Practice exiting the vehicle with your handgun. Each vehicle will likely require a slightly different technique.
So, work with your vehicle and how you carry until you find the combination that works for you. Take your time as you do this… there is no need to hurry while you are figuring this out. It just might come in handy someday.
