i went back to my old agency, the Dallas Police, to qualify today. I retired with 32 years service and go back once a year to qualify. Our issue ammo, in 9mm or 357 Sig, has been Winchester for many years. We were told that Winchester quality has dropped dramatically. Issue ammo is now Hornaday Critical Defense. We were also told that the new ammo is so effective that there is practically no reason to upgrade to 357 Sig. The issues with Winchester were quality control, such as compressed rounds and rounds loaded backwards, and under charged rounds.
