If you're going to carry, you had better be proficient with your weapon of choice. Drawing from your choice of holster/carry location, clearing malfunctions, dropping and inserting mags, being able to hit what you are aiming at. Practice at the range is essential to ensure that proficiency. Most ranges will not allow you to draw and fire but you can practice that dry at home. I'd suggest using some dummy rounds to practice malfunctions if you have a range that will allow. Not a bad idea to set up a double feed in a semi-auto to see how that looks and how to clear one.
