About this product

The F1 Firearms UDP-9 Skeletonized Mermaid AR-9 Pistol is a pistol-caliber firearm designed to chamber 9mm cartridges. It is configured as an AR-type pistol, which means it shares some operational characteristics and controls with AR-platform rifles but is classified as a pistol. This model features an 8.3-inch barrel, which contributes to its compact size and maneuverability. The 9mm chambering allows it to use common pistol ammunition, making it a versatile option for various shooting applications. The pistol's design incorporates a skeletonized receiver, which reduces overall weight and gives it a distinct appearance. The "Mermaid" designation likely refers to a specific aesthetic finish or design element, complementing the skeletonized structure.

Key details

  • Barrel Length: The 8.3-inch barrel provides a balance between ballistic performance for the 9mm cartridge and a compact overall length suitable for a pistol.
  • Caliber: It is chambered in 9mm, a widely available and commonly used pistol cartridge. This allows for compatibility with various ammunition types and generally results in manageable recoil.
  • Capacity: The pistol has a 17-round capacity, allowing for a substantial number of shots before needing to reload. This capacity is common for many full-size 9mm pistols and pistol-caliber carbines.
  • Finish: The firearm features an anodized finish. Anodizing is an electrochemical process that converts the metal surface into a durable, corrosion-resistant, anodic oxide finish. This enhances the longevity and appearance of the aluminum components.
  • Material: The pistol is constructed from aluminum. Aluminum is a lightweight yet strong material, commonly used in AR-platform firearms to reduce weight without significantly compromising structural integrity.

Fit and compatibility

As a serialized firearm, this AR-9 pistol must be shipped to a Federal Firearm License (FFL) dealer for transfer. Buyers should confirm compatibility with any desired accessories or components by consulting the manufacturer's documentation.
