( KTRS ) Missouri lawmakers are advancing a measure that would limit fees to carry a concealed firearm and expand the state’s castle doctrine law.

Under the bill, concealed carry applicants could not be charged additional fees beyond $100 for fingerprinting or background checks.

The measure also expands the castle doctrine law, which gives people the right to use deadly force to defend themselves and their property against intruders. House guests who use deadly force also would be protected under the legislation.

Backers say the bill creates protection from lawsuits, opponents say the legislation encourages use of deadly force.
