Note to self:
Practice off-hand, off-eye.
Be sure to practice reloading magazine or recharging the chamber. In CQB, an assailant that has a tight grip on your firearm can inadvertantly "drop the mag" by pushing the magazine release. Now you have one shot if you are still in CQB. Pretty scary to think about.
Also sobering: Read the story of the "Miami shootout" where an FBI agent had to reload his pistol with his teeth since his arm was blown to bits by the felons Ruger Mini 14....or anything by NYPDs Jim Cirrillo.
