Who bought them? Was it first time gun owners, desperate for some kind of handgun, who didn't know what they were getting or didn't care? Or was it existing gun owners looking to expand their horizons regarding ammo availability? And if all these .357 Sig have been purchased, what does that mean for the future of the cartridge? Will it be one more mainstream, resulting in high production rates of ammo? Or will these guns just sit on shelves in closets, or the back of gun safes once everything calms down again? This isn't a thread about .357 Sig vs [insert cartridge], but a general musing on how increased sales of one of the least popular service cartridges might affect its future.
