Restore fit and finish to your SIG P320 takedown lever assembly with this purpose‑made O‑ring. Molded from durable, oil‑resistant elastomer (nitrile or Buna‑N), the O‑ring fits the takedown lever shaft to provide light preload, reduce lateral play, dampen vibration and operational noise, and improve overall tactile feel when engaging or stowing the lever.
Designed to OEM‑style dimensions for direct compatibility with P320 frames, this small part is ideal for owners, armourers, and gunsmiths performing maintenance, replacing worn soft parts, or eliminating rattles from older pistols. Installation is simple during normal disassembly — slide the O‑ring onto the lever shaft or post before reassembling the lever. Inspect the lever and surrounding components for wear and replace as needed.
Sold individually. Not a pressure seal — intended for fitment and damping purposes only.
