Rhode Island’s new law mainly targets sale, transfer, purchase, and manufacture of certain semi-automatic firearms starting July 1, 2026; it does not generally ban possession of guns already lawfully owned before that date. For semi-automatic shotguns, the law focuses on models with a fixed magazine over 6 rounds ; shotguns with detachable magazines are described as excluded in one report.

What should still be legal

A semi-automatic shotgun is more likely to remain legal after July 1 if it is not a “prohibited firearm” under the Rhode Island definition, meaning it does not have a fixed magazine exceeding 6 rounds and does not otherwise fall into the banned categories described in the law summaries. Some reports also say shotguns with detachable magazines, pistol grips, and folding stocks are excluded from the ban.

What to avoid

The clearest red flag is a semi-auto shotgun with a fixed magazine holding more than 6 rounds. Because the law language is specific and details can change with enforcement guidance or court challenges, the safest move is to compare the exact model’s magazine setup and features against the statutory definition before buying or transferring one.

Practical read

If you want the simplest answer: a typical semi-automatic shotgun with a detachable magazine, or a fixed magazine at 6 rounds or fewer, appears more likely to be legal to own and buy after July 1 under the reported Rhode Island rules. A shotgun with a fixed mag above that threshold is the one most clearly at risk of being prohibited.
