(Old news, maybe, but new to me.)
The Los Angeles County Sheriff’s Department (LASD) has approved for duty use the highly accurate Apex Grade Barrel in the Department’s 9mm Smith & Wesson M&P pistols carried by the LASD Special Enforcement Bureau (SEB). Individual deputies assigned to the Special Enforcement Bureau may now purchase barrels for on-duty use directly from Apex, at special law enforcement only pricing, with barrel fitting to be performed by either the LASD department armorer or SEB armorer. The LASD Special Enforcement Bureau joins the Port Authority of Allegheny County Police Department which has also authorized the Apex Grade Barrel for duty use. Law Enforcement agencies interested in evaluating the Apex Grade Barrel, or other Apex aftermarket upgrades, can contact Apex at (623) 322-0200 for product information and law enforcement agency pricing.
