After I took the armorer class my father in law gave me a 17 he bought years ago. So when I took the advanced armorer school I took it to class. The instructors eyes grew wide. He told me to call glock and they told me it was made in February of 1988 and there were only 35,000 imported that year. Now my father on law is a little anal. He had everthing that came in the Tupperware box including the receipt for the gun which is mint and has adjustable sights. Im not a big 9mm fan even though I have a 26. I like my .40's. I have a 27 but am really looking for a 23. Any idea on how much it might be worth. The instructor told me I could get 2 23's but I'm not too sure about that. I have pics of it but I'm still trying to figure out how to post them. Thanks Ok here ae some pics Wanna kill these ads? We can help!
