Glock 43/43X CoolFire Trainer Barrel

I bought the Glock 43/43x to use in my Shadow Systems CR920x. Its working ok but every so often the slide hangs and does not go back into battery. It appears that the Shadow Systems CR920x barrel is slightly bigger at the breach. Thus, the Coolfire barrel is just a little out of spec (too short). It is still useable though.

This is the second barrel set for me. The first one is for my Glock G45 and both are working fine. I have improved my target score and I am shooting faster with better accuracy. This is the best dry fire training tool I have ( I have several others ). A great training tool that has paid for it's self.

I love the CoolFire Trainer on my Glock 43x!
