Hi guys I'm new here ! I know this is weird but I have a blank firing glock 17, but contrary to it's brothers who fire real ammunition, my G17 has an internal hammer. I was wondering whether while not in use the internal hammer should be left cocked or decocked ? I just don't want to break it because this Is my second one because of sone earlier firing pin issues due to dry firing id be very grateful if anyone can help - Any advice id welcome. Thank you.
