Well I think it has to do with the fact that when gun manufacturers begin production in any given state, things have to be truly dire to force them to move because moving an entire manufacturing operation is a massively expensive affair, and most people who have never run a company - especially one that makes things - miss this fact.I remain puzzled why any manufacturer of firearms or related products would have any facility in Illinois. Or Massachusetts. Or California. Or anyplace in the northeast US.
While I understand the logistical issues involved in relocation, why give any tax money to a state that politically hates your guts? In Illinois Chicago is the tail that wags the dog, let them finance their leftist "utopia" without any help from your company.
