Back when I first got into shooting 9mm, I picked up a G-17
To shoot GSSF matches. After my first match, I ran across a G-17L, and picked it up.
I don't if it was a gen1 or 2.
I was new to shooting Glocks, and had no idea how to fix them. After 30-50 rounds it would start acting up, mostly double feeds. I would take it home and field strip it and clean, she was good for another 30-50 rnds. and start to act up.
I carried it back to the next gun show, and a guy offered me more than I gave for it. I told him I just wanted what I had in it, and how it would do. He gave me what I paid for it and left.
Now knowing what I have learned about them I would never have sold it, just replaced springs and shot it.
But live and learn. I had not found this forum.
It could have been an early gen 1, or worth twice what I had in it ???
