At the risk of starting a flame fest, if the level of "training" you're looking for can be summed up with the following:
1. Work from a holster
2. Shoot while moving
3. Shoot multiple targets (and shoot them while moving)
4. Shoot from concealment
5. Shoot at targets that partially concealed
6. Night shooting
7. Shooting multiple times and shooting rapid fire
8. Reloading
9. Stress Inoculation
That sounds like the very definition of IDPA competition practice. And most of those skills are covered by USPSA/IPSC, too.
Of course, posting this will bring several vehement posts screaming that "IDPA isn't tactical training" -- and they're right, to a degree.
But the list above isn't a complete education in shooting tactics, either. It is, however, a very valuable set of (
elementary level) pistolcraft skills, the development of which is sadly lacking for most "square range" shooters.
If you find yourself needing these (basic) skills improved, and there is no official tactical shooting school close by, look for the nearest IDPA or USPSA match club and go practice with them. At the very least, after a season or two of practical shooting competition, you'll be ready to apply the more specailized training that a tactical school can offer, instead of spending that sizable chunk of money and time to attend a school -- just to have them have to teach you how to holster your gun without shooting your foot.
