Hi folks: I completed Glock Armorer School last Thursday! What a great class! I learned so much! Anyway, it is time for me to place my first parts order to Glock to establish my parts inventory. First, I am a civilian associated with a local Glock Stocking Dealer. That said, I would like some advice on what parts I should make sure I have on hand, which ones to have a pile of, which ones are rarely needed, etc. So...if you were to set up you start up parts inventory from scratch, what would you include? I deeply appreciate your time helping me on this!
