I just got my 2nd conversion barrel. I now have 9mm, 357 sig, and 40 s&w. As I am looking for 9mm, I now realize that it cost as much as 357 and almost twice as much as 40 s&w....when did this happen? I always thought 9 was the cheapest aside from 22.
The 9mm will return to normal prices when demand dissipates. I got 1000 rounds of American Eagle 147 grain in Jan for $240. You have to be ever vigilant and don't squander your cash on over priced ammo.
