Thanks for posting up another video!!!
I'm surprised it functioned as well as it did with that barrel damage.
I'm certain you should be able to get a spare barrel as Tanaka just released the G18 with the short barrel, so they should have just ramped up production on them. Just check that screw once in a while as it does tend to back out after some use!
I like the Evo rounds, however I've also ran the Ctec MildKick rounds through my G17 Evo with good luck. The benefit to me of the CTec rounds are that they are less fiddly - 7mm cap and fewer parts. Also, they are anodized aluminum so they seem to clean up easier, too. Of course, you have to get a different detonator to use them.
Keep the videos coming please!!!
