Hey guys! I'm a newbie so please be gentle hehe. I've been meaning to get a revolver to keep in the house primarily for home defense and taking to the range. After researching different models, I think I'm going with the Ruger GP100 357/38 4.2. I know firearms and ammo are very scarce right now and had a question for you guys. I found a gun shop about an hour away that has one in stock and I noticed its been in stock for some time now while all the other models have been sold out. I thought this was strange that no one was buying it and noticed that this particular model has that blue finish and not stainless steel. I read online that many choose stainless over blue because of erosion even from finger prints? Is this true? Should I hold out until I happen to find a stainless or is it not a big deal?
