I went through a shoot/no-shoot simulator using Glocks, AR-15s, and 870s a couple or four years ago at the Victoria PD. They rented the equipment for a couple weeks for all their patrol officers to go thru, and some citizens got the chance to go thru it on the weekend. It had a number of scenarios, like school shooter, bank robbery, some guys in parking lot that get violent, etc. It was pretty interesting, and afterwords could replay the scenario so you could see where your shots actually landed, depicted by red dots.

So if you can't afford one flat out, see if you can find the companies that rent them to smaller PDs. Maybe you can work a deal to have one at your place once or twice a year when they make a swing thru the Texas PDs.
