A while ago i acquired a Glock 17 during a trade. I know relatively little about Glocks.

It came with a factory magazines and a pmag. What do i need to know about magazine generations? I can't make sense of it. The more i read, the more confusing it gets.

How can i verify that it is factory stock internally? I know the slide stop has been replaced with what looks to be the ghost slide stop. My main concern here is really just of safety.

It also came with a Galloway precision recoil spring and rod assembly. So i guess that is a bonus.

Do i need any special tools to take it down beyond field stripping? Any online guides? I'm very capable of taking things apart and reassembling if i have a visual guide.

This is likely just going to be a range gun and not a carry gun.

Anything else i would know?
