From the LVMPD Firearms Staff:

Attention All AFTTU Instructors and Rifle Certified Officers

Please take a moment to inspect your rifle magazines for the proper duty ammunition. The new Speer Gold Dot bonded ammunition is easily identifiable by the nickel plated cases (Silver in color). If you do not have the correct duty ammunition, please come directly to the range to switch out your ammunition prior to hitting the street.

The old Federal 223E hollow point ammunition is no longer authorized as duty ammunition by LVMPD.
