LANSING, Mich. (AP) — Michigan lawmakers are hoping to encourage gun owners to buy gun safes and trigger locks by temporarily rescinding the sales tax on purchasing the devices.

The Senate voted unanimously Thursday to exempt firearm safety devices from sales and use taxes until 2018.

Supporters say promoting gun safety and making safety devices more affordable could lead to fewer accidental shootings and gun thefts. A fiscal analysis says committee testimony indicated a 60-cent tax break on a $10 trigger lock isn’t enough to change consumer behavior.

The state Treasury Department says the bill could mean about $1 million a year in taxes being collected, much of which goes to the school aid fund. The measure, which was amended to require stores to post notices about the tax holiday, goes to the House.
