You are responsible for your safety and training. If your agency refuses to properly train you, then pay the money, find a local training studio, and get the training. I train throughout the week, and yes it costs money, and yes it requires me to travel and take time out of my busy schedule, but my life is worth it.
Relying on your academy training, or worse yet your gear, to save your life in that moment of crisis is a foolish and potentially fatal mistake. You need to have the integrity and intestinal fortitude to go out and get that training you need to stay proficient in your skill sets.
Find a system that teaches what I have listed above: proper striking technique for both the upper and lower body of the subject, takedowns, ground defense, weapon retention, counters, and defense to strikes, control holds, and stick and knife defense.
You may want to advise your instructor that you are a LEO and have him or her include that in your training regimen. Training in spontaneous attacks that come from multiple directions and multiple opponents can improve your reaction time and allow you to work at a comfortable level under stress. Being able to think and respond correctly under stress is the key. When you cannot think and start to panic, that's when you find yourself getting into trouble.
The key is training for reality and not what looks cool on the mats. Reality is a bad place that none of us want to go, but we must accept that we will go there. The key is to realize and accept this fact and properly prepare ourselves to respond accordingly and prevail in that fight.
