Iowa law in detail
- Iowa sets no magazine capacity limit, so a standard 30 round AR-15 magazine and a full capacity pistol magazine are both legal to buy, own and carry.
- There is no federal limit either. The 1994 federal ban expired in 2004 and was never renewed.
The federal rule
There is no federal magazine capacity limit; the federal limit ended with the 1994 ban in 2004. State limits usually cover sale, transfer and manufacture, and a few also make possession illegal, so a magazine you already own can be legal to keep but not to bring in.
