More people in the market may mean that those buying have less knowledge of handguns in general relying on the knowledge of the salesman to persuade them to buy what he has in stock.
Since blowback pistols are cheaper to make and cheaper to inventory, salesman want to unload what they have rather than order a gun for a customer. If you let someone think too long on the sale, sometimes they will back out. Small, light, cheap, easy to conceal with or without a holster, drop it in a purse, pocket, glovebox, car visor....these are all selling points for these pistols. As more people have them and shoot them, the price of ammo may come down, maybe not. It's a hundred year old cartridge that has it's place.
If I could get the wife to carry anything, it would be something easy to shoot, easy to carry and most importantly something she was comfortble with. My problem with .380 ACP is that there are so many names for that particular cartridge (9mm Kurz, Corto etc....), less knowledgable people may try and force 9x19 into one and get hurt.
2-1/2 cents...
