how do you get to Carnige Hall....thats right...Practice...training for a deadly encounter is no different...you must practice under stress...you must practice malfunction drills...you must practice marksmanship and combat shooting...you must know your weapon inside and out...but most importantly you must train your mind into a warriors mindset / mentality. A gun is not a Talisman it is a tool and if you have it on your side you had darn well be ready to pull the trigger otherwise it is just an expensive paperweight.
