I'm not a SEAL, part of a SWAT team or even an NRA certified instructor. I'm just a guy who enjoys guns as a hobby and who carries for a little peace of mind... just in case. Some readers might be thinking this self confessed non-expert must have unintentional discharges most every time he walks out the door carrying a loaded gun. This might be hard to believe but I never have.
Now while I'm not an expert class operator with a genius IQ, I do have a some good ol' boy Tennessee discipline. LEAVE YOUR CARRY GUN HOLSTERED. This means don't yank out your loaded carry gun for show & tell at church and end up killing a little girl in the pews. Don't whip out your loaded carry gun in a school room full of kids for a scared straight class, double check to make sure your loaded carry gun is empty, then proceed to shoot yourself. Don't jerk out your loaded carry gun in a gun store to see if it fits a holster you're looking at and then catch it on a drawstring of your clothing for a real loud BANG.
Anyone starting to see a theme here?
No matter how tempted you are, how well trained you think you are, how safe you think you are... just leave your loaded carry gun holstered unless you intend to use it in a self defense situation. This technique applies to striker fired pistols too. Works great.
