Condition, Price, and Identification

This listing carries SKU-25020054 and a clear price of $550.99, reflecting the firearm’s stated condition and market position among pre-owned semi-auto pistols. The noted “very good condition” and the specific mention of minor smudging on the top of the pistol are important when assessing value versus a refinished or mint example. The brand is Fn and the model is listed as Various; the category is Semi Auto, which situates the FN 509 in a class known for defensive reliability and modular ergonomics.

Field Performance and Practical Use

Even without explicit caliber details in this listing, the FN 509 platform is widely recognized for a duty-style trigger profile, robust slide and barrel construction, and intuitive controls. For defensive carry or dedicated range time, the overall maintenance history—described here as well maintained by the previous owner—matters more than cosmetic blemishes. When evaluating this piece in person or via the shop page, inspect the slide wear, frame rails, and bore condition to confirm function aligns with the described state.

Maintenance Notes

Minor smudging on the top of the pistol normally indicates storage wear rather than mechanical abuse; regular disassembly, cleaning, and inspection will reveal the true serviceability. Always verify serial numbers and have a qualified armorer or gunsmith perform a pre-purchase check if you plan to rely on the pistol for defense.
