Hi, in Sgt127 and, I'm a free sweater.
Not normal sweat.
Military grade, Haz Mat, weaponized sweat. If I shove a blue gun in my waistband and carry it for 2 hours in the summer in Texas, it will be brown.
My concealed carry guns are hard chromed or stainless.
I have an SP101 and a S&W 65 3" that I carry alot. I have to keep them wiped down too but, not nearly as much.
I coat the grip frames with Boeshield. About every two weeks, I take the grips off and scrub the rust off with a bronze brush and Hoppes. And, recoat with Boeshield or CorrosionX.
I have a Sig P239 that's stainless and alloy. I had all the controls hard chromed. I carry appendix, in a holster. Not long ago, I found rust in the freaking barrel.
I have a nice selection of blued guns of all kinds. But, for carry, I'll take stainless every time.
