So, I’ve been trying to be better about firearm storage, such as removing firearms from bags, storing wood guns barrel down, and storing firearms with the firing pin released, removing pressure from the firing pin spring. I was reading the manual for my new to me 686 Silver Pigeon, and it stated that storing the shotgun with the firing pins released and having snap caps in the gun are essential/highly suggested. But I was thinking, what about galvanic corrosion? Most snap caps are anodized aluminum, and specifically on the aforementioned firearm, my chambers are chromed. I know beretta sells chromed snap caps, but at $50 a pair they aren’t exactly cheap. Is there a chance of corrosion with using the non matching metals? Has anyone had this happen?
