Free concealed carry classes are being offered in suburban Illinois, with teachers saying that training slots are quickly filling up. The On Target Range and Tactical Training Center in Crystal Lake announced on Monday that they would reserve 2 free seats for teachers and other school personnel at their location for concealed carry classes. Co-owner Judy Claxton says that they have expanded the offer now to 6 seats, to accommodate the high demand. The class is offered 4 times a month. Claxton says that the gun range is planning on having a teachers-only class for 24 teachers on March 26th and 27th. State law currently prohibits concealed carry license holders from bringing in guns to school. Tom Dorsch, who is the gun range director of operations, says that the classes will also better prepare school employees in case the law would change.
