Another thread made me look up LaserTraining options and I found this computer program for approx $110. It changes your computer and webcam into a hit/miss/timing tracker for laser training shots. You don't even need a target on the wall you can use a light switch or other item.
You would use any manufacturer of laser that mounts into the chamber or bore that activates for a short time when it hears your hammer or the firing pin hits it.
It won't replace my live fire, only add to my dry fire, sight alignment, trigger pull practice.
Has anyone used this particular program?
