The old buckles and snaps are chrome, but the new ones would be brass in order to match the tie clips and badges.
The department has approved $100,000 to change the buckles and gun snaps. It also plans to spend an additional $200,000 to do the key rings and baton holds.
The department said the change was necessary because uniform standards had become lax with unapproved variations.
A letter to deputies stated that the new look will "promote a more professional uniform appearance."
