Funny, the MK9 my coworkers recovered from the bottom of Puget Sound after more than a month after being dropped by a deputy who dropped it and it's holster over the side while crabbing suffered no rust at all. It did apparently mess up the polygonal rifling, it wouldn't hit a paper plate at 3 yards. Replaced the barrel and it's a tack driver.
It did go from salt water directly into a bucket of oil where it stayed until we took it apart and cleaned it all up. Sent to Kahr for a check up and replaced all the springs in the gun. Still going strong. Heard the detective who ended up with it recently sold it so my grip model is gone.
