Being cops, they have their pistols hanging in a holster on gunbelts in all manner of weather conditions. Being the fish and wildlife type, they spend quite a bit of time on the lake as well and for some reason, irregardless of their maintenance regimen, they are experiencing rust on Generation 4 Glock pistols.
You have three and have had no problem. They have a thousand or so in the field and they have had problems.
By the way, I made no reference to polymer parts corroding.
Since there are 120 counties in Kentucky, and one "possum cop" per county, and perhaps a couple of water patrol officers for the lakes, how can KDFWR have 1000 Gen IV Glocks afield?
Also, no such word as "irregardless".
By the way, I am a former KDFWR biologist.
