How about the Les Moore hall monitor model from Funky Winkerbean???
Others ISDs may take the approach that the Harrold ISD took sometime back.
From the article:
Current law allows districts a great deal of leeway to allow employees or others with concealed handgun licenses to bring firearms on campus, said Victoria Calder, the director of the Texas School Safety Center, but it is an option that very few have chosen to exercise.
One of those outliers is Harrold Independent School District, which enrolls about 100 students near the Texas-Oklahoma border. The district has a policy in place that allows teachers with concealed handgun licenses to bring their guns to school with school board approval after completing additional training.
