Ya Im not sure ,, guys at cabelas said thats something they were doing at glock to try and push the factory reconditioned models.. They had three of these all the same finish and kit with the holster and mag holder. But for $399 and same warranty as a new I took the chance. I took it apart in the store and looks like the only thing they re used was the frame and some of the trigger control parts. The slide and barrel were new along with all the springs ect.
