Kinda looking for things specific to the 590 series. Be it an add-on, modified or aftermarket replacement part, or areas to polish/work. For any possible performance gains.
I carry an all black Jim Wagner reality based rescue folder knife. It's got a half serrated half blunt blade with seatbelt hook on the back with window breaker pommel. I've cut through quite a bit of materials with this, and the seatbelt cutter doubles as a handy bottle opener!
Granted, this method may not be the best by any means... But, if you're putting on a different safety and don't wish to save the old one... You can use a thin flat head screwdriver to pry up on the button and break it in half then use pliers on the screw... That's only if everything else has...
I'm Rob, I currently own a 590 and previously had a 500 cruiser/persuader. I came across this site looking for stock options and after lurking a day finally signed up!
