I agree.......after watching your entire series of 10MM speeds and the Mech Tech Videos I am now an owner of a Mech Tech 10MM CCU.! Wow, this thing is quality and the barrel appears incredibably strong. I haven't shot it yet, working tonight on the Bullet Button. (stupid Kalifornistan). Since I already own 5 Glocks in 10MM including my Longslide I have plenty of FRAMES. Including 3 G21s if need be. I'am going to install an old MILLET red-dot that I had on a 9X25 GLOCK a while back. It's cheap but worked fine for my eyes. For you Kalifornia people, I am considering going 'featureless' so I can use my normal capacity (called High Capacity by the State) magazines. Otherwise I am restricted to 10 round mags with the bullet button. This would require I install a 'wall' behind the grip so it's not a pistol grip anymore. Just thinking about it, nothing firmed up yet. Be well............Bob Wanna kill these ads? We can help!
