Much obliged Pensfan.
I still aspire to take a formal Glock Armorer's class at some point. I appreciate that from a perspective of growing up with guns,many feel that these things are fairly easy to take a part and put back together (and I'm sure they are). But part of *my* interest in that class is to learn as a noob, and part is to learn how the learning takes place, as an Engineer in the Training and Simulation industry.
Thanks again.
