Matching status ≠ identical law — details, limits and penalties can still differ.

Illinois to Missouri: common questions

Do the laws change when you drive from Illinois to Missouri?
Yes — 9 of the 13 categories LawLert tracks have a different status in Missouri than in Illinois: driving, hunting, firearms, fireworks, alcohol, knives, cannabis, gambling, taxes. Each is listed on this page with its current status, the official source it came from, and the date it was last verified.

Missouri: Restricted — During firearms deer season, all hunters must wear a hunter-orange cap/hat AND a hunter-orange shirt, vest or coat, plainly visible from all sides. In Illinois the same category is Conditional.
What are the firearms laws in Missouri if I'm coming from Illinois?
Missouri: Conditional — Legal when possessed in compliance with federal law. Under RSMo 571.020 possessing a firearm silencer is an offense only if done "in violation of federal law," so an NFA-registered suppressor is lawful. In Illinois the same category is Restricted.
Is my Illinois concealed carry permit honored in Missouri?
Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Missouri's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/MO/reciprocity. Permitless carry, where a state allows it, is a different question again — it does not make an out-of-state permit valid.
