Blue wears off with holster wear and the standard steel doesn't resist pressure and gas cutting like stainless. I was around in the early 80s when stainless guns were almost impossible to get in any other make than Ruger, and my first gun was a stainless Ruger Security-Six. I went up in the mountains behind Provo, Utah, and found a place where people were shooting. Having never fired a handgun, I noticed that the others shooting were making a lot of noise. Soon my ears were ringing and others, noticing I was new at this, gave me some hearing protection and taught me the basics.
Something else I learned as a student was, "Hey, this is expensive!" So after cleaning my gun, I zipped it up in a pouch and returned to the gun store. I left with an RG .22lr cowboy pistol, chrome plated with cheap, brown plastic grips. That I could afford and I bought four boxes of ammo and yes, some hearing protection.
Say what thou wilt about RG, I had more fun with that little gun than just about any other. Not only did it look like the cowboy gun I had as a kid, it didn't weigh that much more, either. Plus I didn't have to worry about losing it. Still, about six to eight months later, I traded it in for a Ruger Standard Auto. What a gun! It was blued, but I wished they had made it in stainless. From then on, I haven't bought blued guns unless left with no other choice. The gun I never had was the S&W Model 66 with recessed chambers and pinned barrel.
I had enough friends who complained about rust forming on their blued rifles within an hour of being exposed to morning drizzle. I also noticed that when it began raining, the folks with blued handguns packed up their stuff and left while those of us with stainless guns continued shooting without a second thought.
When I bought one of the first S&W 629s, I had to agree to let my friend and dealer display it on his shelves for a week before picking it up. Never did shoot that gun and it was one of the most magnificent guns I ever had. When I picked it up, people at the store wanted to touch it and dry fire it. It was like being a celebrity.
So white guns are more natural to me than blued guns. And even though products like BreakFree finally allowed shooters of blued guns to be fired in the rain, it was too little too late. Besides, BF worked just fine on stainless guns. As for those who claimed these stainless pistols would be too visible in low light, I took a blued gun and a stainless gun, both Ruger 4-inch Security-Sixes, downstairs one evening in very subdued light. Never could see that much of a difference. If you're a hunter and don't want any glare, simple wax shoe polish solves that problem on both stainless and blued guns.

range gun and the latter a great hiking, hunting and camping gun.
