I know this is kinda old, but I thought I'd mention something for the non-Iowa residents. Iowa law is extremely fuzzy about loaded magazines. Depending on how you read the law you could be in trouble for a loaded mag even if it is not in the gun. There is movement to try and change this law as it is ridiculous, but I know several people who have been hastled by LEOs about loaded mags. Most that I know transport mags empty. Just a word of caution.
