"International Customers
If you live outside of the United States and your Ruger® firearm requires service, please contact the Ruger distributor(s) in your country.
Select a Country
If you do not see a distributor listed for your country, please contact our Export Department directly (Telephone: 603-863-3300, Fax: 603-863-9371), with a full description of your Ruger firearm, serial number, and details of the problem you are having. It is very costly and time-consuming to return your firearm to the U.S. for service, and we may be able to resolve the problem locally. Please understand that the export of firearms always involves U.S. State Department or Commerce Department approval and licenses, which can take some time to obtain."

Jovince, Ruger doesn't put a warranty in writing , but the reality is that Ruger will correct any manufacturing flaw or defect on any firearm for as long as you own it. They will typically pay shipping both ways. It doesn't matter if you are the original owner or not, and it makes no difference who you bought it from. Have a great day!
