Mantis X Training System - Anyone Else Using it?

I'm having a lot of fun using the Mantis X Training System. Anyone else here using one? I need some reasonable options to install on my 1911 that doesn't have a rail. Any ideas?

 

I've been playing with mine on a SIG co2 air gun. It's been interesting, but I haven't been good about staying with it.

 

I have used this, and I learned that if I paid attention to the fundamentals, I "shot" better.
Then when I go to the range, I also learned that if I paid attention to the fundamentals, I shot better.
Of course the range cost more, but it was also more fun. For the 1911 for dry firing, you could probably attach it to a dowel and stick it in the bore to see if you like it.
I got this because Mas recommended it. He also recommended a lighted toilet bowl illuminator which was awesome, but it stopped working. If Mas recommended an inflatable robotic home defense dog, I would probably buy it, my faith in him is that
great.
