- Do the laws change when you drive from Missouri to Iowa?

- Is my Missouri concealed carry permit honored in Iowa?
- Permit reciprocity is decided separately from the firearms status shown on this page, so it is not answered here. LawLert publishes Iowa's recognition list, with the statute or agency page behind it, at lawlertapp.com/firearms/IA/reciprocity. Permitless carry, where a state allows it, is a different question again — it does not make an out-of-state permit valid.
- How current is this Missouri to Iowa comparison?
- Every rule on this page stores the date it was last checked against its source; the oldest on this comparison is 2026-05-31. Every rule LawLert publishes carries a source URL, and every correction it has made is public at lawlertapp.com/how-we-verify. Laws change — confirm anything consequential against the linked source.
