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.

Legislation to exempt firearm safety devices from sales and use taxes until 2018 is up for a vote Thursday in the state Senate.

Supporters say Michigan should do all it can to promote 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 a broad interpretation of “firearm safety devices” could mean about $1 million a year in taxes being collected, much of which goes to the school aid fund.
