I got this gun about two weeks ago and took it apart first thing. Watched the videos a couple of times before hand.
First time putting it back together I had some difficulty. Didn't want to force anything, somehow got the barrel out of alignment, put it down, took it apart and went back through it. Got it back together so I took it apart right then to see if I really was making a mistake.
After about 4 times of doing it I can do it without a video or feeling scared. I felt the same way when I got my first revolver and my first semi auto.
