Cheese, the nickel finish resists saltwater contamination.
I realize that this is why it has that finish.
I'll put it to you this way, I like guns in any color, as long as that color is black.
I guess there's a little bit of Mr. Ford in me.
The only guns I have that aren't black are my 2 Kahr MK40 Elites and my 2 Smith & Wesson 642s. Everything else is black somehow, either blued, anodized, or some other similar finish. I didn't get the MK40 Elites in black because you can't, and I didn't get a 442 over a 642 just because.... well, actually there is no good reason. I didn't seem to care as much with a pocket J-frame I guess.
But hey, if you guys like it - that's great.
I'm just looking for flat black, specifically parkerized in this case if possible. Fortunately, I'm moving very very very far away from the current saltwater environment I live in. 1,500+ miles away (and I'm looking forward to it!) I will be in land of 10,000 lakes, but I think they're all freshwater.
