July 26, 2000 MILWAUKEE, Wis. - Master Lock Co. of Milwaukee is recalling 752,000 gun locks because their two sides can be manually separated without keys. The company said it was initiating the recall to prevent any mishaps, although no reports of gun locks being disabled have been received. The locks involved are sold separately or in combination with certain Smith & Wesson and Walther handguns. Each half of the lock surrounds the trigger with a one-inch locking post connecting them. The words "Master Lock Tough Under Fire" are imprinted on the lock's black rubber pad. The locks also have yellow stickers reading, "Warning! Do Not Use On a Loaded Gun!" Those sold separately were packaged with a green-and-black cardboard display card and instructions. Included are model Nos. 90, 90DSPT, 90KADSPT, 90TSPT, 90DS&W OR 90TS&W. The packaging also contains the words: "Made to exclusive Master Lock specifications in China." The locks were sold at Wal-Mart, Kmart, Gander Mountain and Sports Authority between June 1999 and July 2000 for between $8 and $12. Consumers are urged to call Master Lock at 800-944-1380 for a free replacement. They're also advised not to use the defective locks.
