Many of the military and law enforcement are not taught the best techniques or fundamentals. It is alarming the percentage who do not have sound fundamentals and what they do not know. Look for a NRA Certified Instructor in Pistol in your area. It sounds like you may have a limited budget, but not all certified instructors charge to give instruction. Here are a couple of links of Todd Jarrett. If you look at 'From The Theater' on the Firearm Review Forum, there are four more links to Todd Jarrett on proper shooting form and techniques. Notice how little muzzle flip his firearm has and how his hands do not move. He is very efficient in how he does move.
