I've had sidearms & guns since I was about 19. I've
never had any weapon retention problems or gun grabs while doing armed work or while OCing.
If I
did open carry more(it's not allowed for gun owners where I live), Id use a level II type security holster. Weapon retention would be more important to prevent grabs or accidents.
I once had my Ruger GPNY .38spl slide out of a Blade-tech holster(cross draw) & hit the pavement.
Not good!
