Hey everybody, I just bought my first handgun a bit back and yes, it's a Glock. I picked up a used G17 from a friend of mine and so far I couldn't be happier. I took it into my local gun shop and evidently I had the gunsmith's stumped. They said they had never seen a Glock like mine and they weren't sure what to make of it. They suggested coming to a forum such as this and seeing what the experts had to say....
Well this is my G17
Any thoughts?
