I got the call today, I finally got my hands on one... a Glock 21 Gen 4.
I'm not a big fan of the Gen 4 17's and 19's, I believe Glock dropped the ball with the Gen 4 changes to these pistols. The 9mm just doesn't work well with the new spring design, the guns are over sprung and Glock is trying to deal with it.
But the .45 ACP, now that has potential. I'll find out here soon, and of course I will document my adventures on video.
Meanwhile, here are some baby pics.
