Where do you get your training/techniques and/or advice?

As a professional protective security operator, I carry everyday, either concealed or open. And that doesn't change when I return home to the states, where I carry concealed. Now, I've had a ridiculous amount of weapons training, both in the Marines and in my current profession. I was looking around AZ where I live and found the majority of training/techniques come in the traditional "instructor and course" model. While getting some good one on one training and advisement is extremely beneficial, I feel like there needs to be programs out there with more follow up and continuing actions beyond just a 2-3 day or week long course. As we all know, your shooting skills are extremely perishable, especially pistol work. I stay up on my skill set because it's my profession. And unfortunately there are too many who buy a gun, fire off a few rounds, get a permit, stuff it in their jeans, and they're good (in their opinion). There's a wealth of knowledge and expertise out there, especially with all the infantry/special operations combat vets that receive even more training in my profession. Anyone resonate with this? What would you like to see more of or not getting enough of?
