If you had your choice between a stainless Walther PPK/S or a blued Sig 232 for a carry gun, which would you get? Both are the same caliber (.380), and roughly the same price (232 is a little higher). The Walther has the advantage of being stainless which would be good for corrosion resistance in an all-day carry situation, but it's reliability is not as consistent as the Sig. The Sig has a more reliable reputation, but it's a alloy frame which is not as durable as stainless, and it has a blued finish which can lead to corrosion in humid weather and extended holster wear.
If those were your only two options, which would you choose, and why?
