we all try our hardest at what we do, it's the great ones that understand its not what you do, it's how you do it and accomplish it and embrace there strength despite anyone's opposition.
I have a padlock, the masterlock 528 that has that same keyway, except its a gun lock. The lock is a piece of crap, try a half diamond, and you'll probably get it open in about 30 secs. The one I have has 2 spool pins in it, if that helps.
