While all reloading saves money, the 9mm is not the best choice for handguns.
With bulk ammo available for under $200 per thousand, unless you are going to shoot a whole lot of it, or require a load not available otherwise, it's not a big savings.
I used to, but don't anymore.
I'd rather spend the time and effort for the costlier handgun calibers.
Lock the doors, they're coming in the windows.
