Connecticut restricts magazine capacity to 10 rounds.
Connecticut restricts magazine capacity to 10 rounds. Magazines holding more than 10 rounds cannot be sold and shipped into the state. This is one of fourteen states plus Washington DC with a state-level limit; the rest of the country has no federal restriction, so a standard 15- or 30-round magazine is legal nationwide except into Connecticut. The rule applies to the magazine itself, not the firearm. This page covers what you must block at checkout, how to set up the geo-blocking in Shopify, and why your payment processor will ask to see proof you are enforcing it.

Nothing about the product is unlawful nationally — it is unlawful into Connecticut, which makes this a catalog and geo-blocking problem rather than a business-model one.

What this means for your store
If you sell higher-capacity magazines, you must refuse all Connecticut orders for those products or route them to a fulfillment partner in a state where the sale is lawful and have them drop-ship from there. The second option requires a separate shipping profile and careful catalog management, because the same SKU must have two behaviors — blocked in Connecticut, shipped from elsewhere elsewhere. Existing customers in Connecticut cannot be re-shipped a magazine that violates the limit if they ordered before the rule, and you cannot modify their order to comply. Shipping a 15-round magazine to Connecticut is a felony-level offense in the state. Processors flag this heavily: a store shipping firearms accessories into states that prohibit the product is a high underwriting risk, even if the accessory itself is legal federally.
The control that actually enforces it
You control this at checkout, using Shopify shipping profiles or market restrictions. The simplest method is a per-product shipping profile that blocks Connecticut. Every magazine SKU over 10 rounds needs a profile that excludes CT. You can also use Shopify Markets to disable sales into Connecticut for those products, or set a shipping restriction at the variant level. If this is only a note in a spreadsheet or your head, you will eventually ship to Connecticut by mistake — and the processor will see it and act. Evidence of the control is what an acquirer wants: screenshots of the shipping profile or market rule, and order history showing zero Connecticut orders for restricted items over the last six months.
Why an underwriter cares
Your acquirer views shipping accessories into a state that prohibits them as evidence of weak catalog controls, separate from the legality of the product itself. Magazines are federally lawful, so the risk is not the product — it is that you cannot execute a basic geo-block. A processor underwriting a firearms accessories merchant will demand proof that restricted-capacity magazines do not ship to Connecticut. That proof is a screenshot of your Shopify shipping profile or Markets rule, and zero Connecticut orders for those SKUs in your recent transaction history. Without it, the underwriter must assume you will ship there again, and will reserve or decline you on control risk alone.
Frequently asked
Can I sell any firearms accessories into Connecticut?
Yes, but only accessories that comply with Connecticut law. Standard magazines with 10-round capacity or fewer are legal and can be sold into Connecticut without restriction. Magazines with capacity over 10 rounds cannot be shipped there. Other accessories — sights, grips, slings, cases, ammunition — are not subject to the magazine capacity limit. Check whether Connecticut restricts the specific accessory you are selling, because the restriction applies to the magazine only, not the firearm or other parts.
What happens if I accidentally ship a magazine over 10 rounds to Connecticut?
You have committed a state crime. The customer could face criminal charges, and you could be liable for knowingly or recklessly shipping a prohibited item into the state. Your processor will see the order and the state law, flag you for weak controls, and may freeze or close your account. The cost is not just compliance — it is your ability to process payments at all. Always verify your shipping profile before going live in Connecticut, and check your order history quarterly to catch mistakes early.
How do I set up the block in Shopify?
Use Shopify shipping profiles or Markets. Create a shipping profile for each magazine SKU over 10 rounds that excludes Connecticut from the eligible locations. Tag the SKU so you can apply the profile in bulk. Alternatively, use Shopify Markets to disable sales of those products into Connecticut. The method depends on whether you ship to many states or just a few, but either way the block must be at the SKU level, not at checkout. Document your rule in writing so you can show a processor or auditor exactly how you enforce it and when you put it in place.
