My J-frame M60-7 gets carried against my bare skin in the summer when I wear a Polo, "Hawaiian" or T-shirt and I have not had any issues with the finish. It rides in a Kramer Horsehide Scabbard and most of the gun is in the holster, so only the grip area really touches my skin, but still no rust of any type after 25 years. I do own an Airweight, but have never really carried it much because I prefer the heavier stainless steel version for use with the Buffalo Bore +P ammo I carry. Just about the only time I will carry the M37 is when I have to wear a suit & tie and like the lighter weight. I stoke that with standard pressure BB ammo.
