AUSTIN, Texas -

Changes could soon come to concealed handgun licenses thanks to a new bill advancing in the Texas Legislature.

Under a new bill, concealed handgun license holders in Texas would be allowed to carry a revolver or semi-automatic pistol, regardless of what they trained with on the shooting range.

Current law certifies license holders to carry only the type of gun they used to get their license.

The bill by Sen. Craig Estes (R-Wichita Falls) would allow them to carry either model.

The bill passed the Senate on Tuesday night and still needs a House vote to send it to Gov. Rick Perry.

Texas has more than 500,000 concealed handgun license holders.

The bill also would prevent cities from banning possession of an air gun.
