I have been thinking of taking GLOCK's Armorer Course. I am trying to decide if it is worth the time and money ($150). I should say that I am not interested in the actual Certificate. I just want to learn how to maintain my own guns properly, and avoiding those nickle and dime charges at my gunsmith.
My question is:
Would I be better off taking the course or just investing some time and money in manuals/dvd's?
Any advice is appreciated.
