I was inquiring at the LGS today about all the 38 Super ammo being rated as +P. The owner stated I could shoot 9 Largo (Bergmann-Bayard) in the 38 Super but could not shoot the +P in a gun chambered in 9 Largo. He had several boxes of CCI Bergmann-Bayard 9 Largo. With the 9 Largo being cheaper does anyone know if his statement is true? Any other insight would be greatly appreciated.
