It had better be off the trigger if you are holstering your handgun. A lady at Gunsite learned that yesterday. This is something that happens from time to time and is typically the product of trying to put your gun away too fast. Truth is, there are very few instances where you will need to put your handgun away with any speed at all and probably none unless you’re a cop.
At any rate, as Gunsite instructor Chris Weare pointed out, even Gunsite instructors – with all their super powers – cannot move fast enough to stop you from shooting yourself. Which is why you should listen to what they say and do your best to not deviate from their instructions. Hey, finger off the trigger until its time to shoot.
This photo shows the liquid free results of holstering with your finger on the trigger. The shooter will be OK, but will be permanently tattooed thanks to a 115 grain 9mm bullet from Doubletap and her finger; which was being poked somewhere it should not have been at precisely the wrong time. Fingers can be terrible things. Be careful where you put them.
