Just picked up a very nice Generation 2 Glock 23. Pistol is in like new condition except the breach face is covered in what appears to be some kind of tool marks... or? Should I be concerned about this or just fire away and forget it? Have owned many Glocks but never have I run in to anything like this. Any advice would be appreciated.
