The FN 509C TACTICAL offers a taste of reliability and accuracy you can trust from any FN product. Designed as an EDC (everyday carry) pistol, the FN 509C TACTICAL offers a unique combination of great ergonomics, dependable accuracy, and affordability.

The FN 509C TACTICAL pistol is the product of extensive testing, research, and development. Its construction is based on the veteran FN 509 frame with the added addition of a 4.5-inch cold hammer-forged stainless steel barrel that is threaded for 1/2-28 UNEF suppressors and other muzzle devices.

The FN 509C TACTICAL's ergonomics possess the normal injection-molded polymer grip and frame construction found in most polymer-framed handguns. It has a textured grip that allows for secure purchase even in the moistest of hands and is offered in two variants: black or flat dark earth.

The 30-millimeter fixed stainless steel sights offer shooters a good sight picture and a crisp sight alignment. The sights are adjustable with a set screw and offer a large, easy-to-see fiber-optic sight picture. Additionally, the FN 509C TACTICAL has an ambidextrous slide stop and magazine release for added convenience.

The biggest benefit of owning an FN 509C TACTICAL is that it has proven reliable in harsh environments, especially those with sandy or dusty conditions. For the most part, the FN 509C TACTICAL has proven itself to be incredibly reliable and without many issues. This is a testament to FN’s commitment to quality control and craftsmanship.

Furthermore, the FN 509C TACTICAL is incredibly accurate. It features a precision-machined barrel and stainless steel slide that gives the gun a great circumference. The barrel is also fluted for greater accuracy. The FN 509C TACTICAL is not a competition gun and the accuracy it offers is more than adequate for personal defense applications.

For the price, the FN 509C TACTICAL is an excellent choice for a sidearm. You won’t find many handguns with such great ergonomics, accuracy and reliability at this price point. Although the gun is predominantly constructed of polymer, the grip and frame are ergonomic and comfortable and the overall quality of the handgun is good.

In terms of maintenance, the FN 509C TACTICAL is relatively easy to clean and maintain. The stainless steel slide and frame helps to make the overall process simpler and more efficient. The pistol can also manage heavy use without too much of a problem.

The only area the FN 509C TACTICAL falls short in compared to other EDC handguns is its magazine capacity. On paper, it is able to hold 17+1 rounds of 9mm, which is one round less than other handguns on the market such as the Glock 19 and the Smith & Wesson M&P Shield. On the plus side, its shorter barrel and grip length help to make it more concealable.

Overall, the FN 509C TACTICAL is a fantastic choice for those looking for a reliable and accurate EDC handgun. Its no-nonsense construction, reliable performance and accuracy make it a great choice for home defense, concealed carry, or even as a backup duty/competition pistol. The affordable price and great ergonomics also makes it an attractive option for those looking for a quality duty/carry gun without breaking the bank.
