Terry, Ruger has a couple 380's. If you mean the new Ruger security 380 and Ruger lcp max yes they're all double stack. The Ruger lcp is a single stack design. Hope this helps.

THE NEW RUGER IS NOT A TRADITIONAL DOUBLE STACK WHERE CARTRIDGES ARE SIDE BY SIDE. CARTRIDGES ARE IN A TEN AND TWO O'CLOCK POSITION IN ORDER TO KEEP THE GRIP PROFILE THINNER AND EXPAND CAPICITY. HOPE THIS HELPS

The Ruger Security .380 and the Ruger LCP Max are both double stack .380's

Hi Terry, yes Sir the Ruger Security .380 and the Ruger LCP Max are both double stack .380's : budsgunshop.com/product_info.php/products_id/151753/ruger+sec-380+.380+acp+3.42+15rd+black?trk_msg=7a26g5v11uk45015rnn8c8egus&trk_contact=q7cc1d7b5gm02haee5dgag423c&trk_sid=1g7sbf552dc8pljcksks7kpv40&trk_link=8fka96nq9jo4vck5qmt2dmt9to&utm_source=listrak&utm_medium=email&utm_term=https%3a+budsgunshop.com+product_info.php+products_id+151753+ruger+sec-380+.380+acp+3.42+15rd+black&utm_campaign=bgsrug031523 --------------------------------------- budsgunshop.com/product_info.php/products_id/154119/ruger+lcp+max+.380+acp+package+with+steel+handgun+case -------------------- Cheers and stay safe!

Terry, if you mean the LCP Max, yes it comes with 2 double stack 10rd magazines. If you mean the Security .380, that also uses double stack magazines. The LC .380 uses a single stack magazine. Have a great day!
