I have been to all of the sites that say they can date my 36 and they have ERROR messages or working on site. My G36 I purchased used and is in 98% shape. No box so no fired casings to check the date. Can anyone advise year made?? SN GDL 3XX. Thanks in advance as I am sure everyone gets tired of dating glocks on forum. Jim Wanna kill these ads?
