I carry an Sig P365 daily as a construction equipment field mechanic. It is carried in my front pocket in a sticky pocket holster. This gun has been through rain, sweat, diesel, hydraulic oil, as well as getting filled with dirt and sand. It gets cleaned once a month if I remember to even clean it. The finish on these guns is incredible, other than the occasional surface rust, it has held up amazingly well. The magazine around the Magwell does get a little rusty, however with a little cleaning it’s good to go. Been carrying this pistol since 2019 and have yet to be disappointed with it.
