Frequently Asked Questions

  • What is my warranty and how does it work?

    Warranty Information

    FMK Firearms warrants to you, the original purchaser of a new firearm, that for lifetime from the date of purchase in the United States, your FMK firearm will be free from defects in material and workmanship.

    If you make a claim within the warranty period following the instructions given in this warranty, we will, at our option, repair the defect(s), or replace the firearm at no cost to you. If we send you a new firearm, we will keep the defective one.

    First, when you purchase your firearm, you must complete in full either the online registration form or mail the warranty registration card to us within 30 days of date of purchase. Then, if you discover a defect, you must notify us or an authorized FMK warranty repair center immediately. You may either call, email or write to FMK at:

    FMK Firearms, Inc.
    Consumer Service Department
    1025 A Ortega Way
    Placentia, CA 92870
    714-630-0658
    support@fmkfirearms.com

    PLEASE DO NOT RETURN FIREARMS TO THE ABOVE ADDRESS. If we decide that it is necessary for you to return the firearm to the factory or an authorized warranty repair center, we will issue you an RMA number and the sender must prepay freight. We will not accept C.O.D. shipments or packages without RMA numbers visible from the out side of the package.

    We will not cover damage of your firearm caused by:

    • Failure to provide proper care and maintenance
    • Accidents, abuse or misuse
    • Barrel obstruction
    • Hand loaded, reloaded or improper ammunition
    • Unauthorized adjustments, repairs or modifications
    • Normal wear and tear

    FMK Firearms excludes and will not pay incidental or consequential damages under this warranty. By this we mean any loss, expense or damages other than to repair the defects in the firearm or replace the firearm. No implied warranties extend beyond the term of this written warranty. PLEASE NOTE: Some jurisdictions do not allow exclusion of incidental or consequential damages, or limitation on how long an implied warranty lasts, so the above exclusion and limitations may not apply to you. This warranty gives you specific legal rights and you may also have other rights.

    NOTICE: It is illegal to ship a firearm with ammunition in the firearm or in the same packaging. Firearms and ammunition must be shipped separately.

  • What kind of ammo should I use?

    Most factory ammo will work fine.  Remington UMC and Speer Lawmen 115g are what we recommend for the pistols.  We have found that light reloads, Russian steel case ammo and Winchester white box do not work consistently.
