You didn't say what size gun you want but my CZ P-01 has proven to be very corrosion resistant. I do tree removal, trimming, logging and firewood, which means that the gun is regularly exposed to copious amounts of sweat, dirt, potentially acidic sawdust, rain etc. Went from a Glock to the P-01 about a year ago and it's doing very well, better than the Glock actually. I am religious about keeping it oiled, especially in the summer time.I own glocks and like them, But i want something with a safety that's easy to shoot. also what if it gets submerged in freshwater is detail stripping a must? I've noticed some guns look very difficult to detail strip.
Edit. I have the Omega version, which can be used in DA/SA or SA with safety. I carry it DA/SA.
