I have been carry Glocks for a couple of years. Safety has always been priority one. Safe Training and Safe Practice. Before I carry it loaded, I carried it at home in the holster (unloaded). I carried it around the home loaded with Snap Caps. I practiced drawing from concealment UNLOADED. I practiced drawing from concealment with Snap Caps. ONE MUST ALWAYS BE DELIBERATE AND HAVE AWARENESS OF THE FINGER IN RELATION TO THE TRIGGER. ONE MUST REALIZE THAT THE GUN IS ALWAYS LOADED. Despite no external safety, I feel completely confident carrying a Glock loaded. When I remove the Glock from my holster, my finger is always outside of the trigger guard. When I place my Glock in my holster, it is ALWAYS before I put the holster onto my belt. If I practice drawing, my finger is ALWAYS outside of the trigger guard, until it is cleared from my holster. How people shoot themselves: NOT REALIZING GUN WAS LOADED Re-holstering a pistol into a holster WITHOUT LOOKING Not paying attention to position of finger in relation to the trigger when drawing or handling Using improper technique when drawing from a Serpa Holster Some advocate the Israeli Draw: Loaded Magazine, Empty Chamber and racking the slide while drawing. That may work, if you have function of both hands/arms. If you have to shoot one handed because of unforseen injury, you're pretty much Dead in the Water, as I heard them say in my Navy days. Anyways, do what works BUT DO WHAT IS MOST COMFORTABLE TO YOU. This is my way. You have your own way.
