Range days are not as much as I would like them to be due to my schedule so, most of my practice somes from Airsoft training.
From concealment, practice clearing garment, draw stroke, front site ack, trigger squeeze, and follow-up on second shot. Repeat, time and time again until it is memory. Once memory keep practicing to keep it in memory.
I also work on clearing malfunctions when I am at the range. I have a couple of bullets loaded with a popped primer and no powder. I will mix it in with the other rounds before I load up my mags. This way I don't know where it is in the order and will be suprised when I comes up. Always practice your malfunctions because if you are not familiar with them it can cost you your life.
