The August issue #211 of USCCA's Concealed Carry Report has a reprint of an article from it's magazine.
The magazine and the report are both copyrighted, so I cannot post it here.
The article gives good instruction on how to practice techniques when your range prohibits practicing these techniques, like drawing from a holster, firing at multiple targets, rapid fire, firing while moving and others.
It lists alternative methods of training that combine live fire and dry fire drills to approximate the technique.
I found it useful.
Here is an excerpt of the article introduction. If you are not a member of USCCA and are interested in the article, you might look into joining.

...On the range, practice a smooth presentation from the low ready to the target...
by Kathy Jackson
At the end of a defensive handgun class, I was speaking with one of the students and suggested that if he wanted to retain what he had learned, he would absolutely need to practice the techniques and drills we'd done in class. With a downtrodden look, the student replied, "My range won't let me."
This article is for him, and for people like him.
Please note: the drills suggested below will not take the place of live fire on a hot range, and they are not intended to do so. Nor will you be able to teach yourself how to perform any of these advanced skills from the ground up using these adaptive techniques. However, if you have already learned these skills elsewhere, preferably under the watchful eye of a competent instructor, these adaptations to restrictive ranges may help maintain the proficiency you've already acquired. And that's all they are intended to do.
