When I borrowed my grandpa's Colt 1911 to check it out, I had to go onto Youtube to learn how to field strip it. I've done the same thing for my M&P, just haven't actually completely stripped that gun yet.

With my CZ, I've had it completely disassembled, except for the trigger group, and did that just from Googling how to take it apart. If I left it up to the manual to tell me what to do, my gun would never have been cleaned and stored in a safe with an action lock still on it.
