You can also save up some money and go to one of the many professional training sites in the US such as Gunsite, or attend Bob Pincus' ICE training when it comes to a location near to you. You may find that some local security companies offer advanced training, as Signal 88 does here in Omaha. Also, try to find a "blue gun" for your make and model of firearm and practice drawing (using both strong and weak hands) extensively (this will be an eye opening experience and may well change how you carry your gun). If you carry a Glock, you can find a plastic training barrel for the weapon that will allow you to use the actual weapon as a training aid, and they also make a training magazine that duplicates the weight of a loaded magazine. Another thing that you cannot do enough is to load magazines with dummy rounds and practice magazine changes (or speedloading if you use a revolver). Practice over and over again until the mag "slides right in" nearly every time you do it. Dummies also let you practice malfunction drills, including double feeds that can be tricky to clear. When you are at the range, load a few dummies in random locations in your magazines and then mix them up so you don't know where they are in any given magazine. This will help you learn to clear malfunction and swap magazines quickly. Much of this will be learned in the better advanced classes, but there is no reason that you cannot work on these yourself.
