Ok, that sounds good (book). But as a consumer I have to ask why Glock wouldn't list factory production info on their site. I love the internet - if I want to buy something it is great to go to the manufacturers website and get the real in depth trusted info... this is where Glock.com fails
Try www.teamglock.com where you can also print out and fax a request for a free copy of the Glock annual. The Glock Web Site is a very low priority item with Glock. Trying to keep the manufacturing pace close to the sale pace is number one priority. Keep in mind that Glock's primary Global business is military and law enforcement sales.
