Interesting concept of a round counter display on the back of a glock slide.

Shows how many rounds are in the mag.
Counts down as rounds are fired.
Display shows if a round is in the chamber.

Interesting concept. If it wasnt that you have to send it to Radtec to be installed I might get one. Oh and there is that 1000 price tag...

One of the reasons I prefer glocks is the simplicity of design and function which IMHO makes it so reliable. Not looking to do anything to it that changes aspect of the firearm.
This looks way too FPS gamey to me.

The other issue I would have is the display interfering with night sights.
