FN BLK Semi Auto: Compact Defense with Holster & Mags

Choosing a compact, reliable semi-automatic for defense or range work means balancing size, ergonomics, and the accessories that make a pistol mission-ready. For those who want a mid-size platform with a modern optic-ready slide, a practical holster, and extra magazines included, this listing deserves a close look.

FN 509 MIDSIZE MRD [BLK] is offered in GOOD CONDITION and comes with the ORIGINAL BOX, a HOLSTER, and 2 MAGS for a price of $575.99. This is a semi-auto platform from Fn with various model configurations in the 509 family; the “MIDSIZE MRD” designation identifies it as a mid-frame, optic-ready example designed to accept a mini red dot (MRD) plate and footprint.

Why the FN 509 MIDSIZE MRD [BLK] Stands Out

FN has built a reputation on durable duty pistols with thoughtful ergonomics and consistent trigger feel. The 509 series is notable for its rugged construction and factory support for optic-ready slides. The mid-size frame makes this model versatile: large enough for a full firing grip and controllable recoil, yet compact enough for many concealed-carry setups or duty use when paired with the right holster.

Optic-Ready Versatility

The MRD configuration means the slide is cut and prepped to accept a mini red dot. That opens options for faster sight acquisition and better target tracking in defensive scenarios. Because this listing includes a holster, you’ll want to confirm whether the included holster supports an MRD-equipped slide or if it’s for a suppressor-height iron-sight configuration—details are on the product page.

What’s Included and Why It Matters

Listings that include accessories reduce the immediate cost of a ready-to-use setup. This FN 509 MIDSIZE MRD [BLK] comes with the original box, which helps with storage and transfer of ownership, a holster to allow immediate carry or range use, and 2 magazines so you can rotate reloads during training or have a spare on the belt. The listing states GOOD CONDITION—buyers should view photos closely and check the product page for any wear notes. View product details and pricing

Practical Benefits of Included Accessories

Two magazines are a minimum for defensive readiness: one in the firearm and one in a magazine carrier gives quick reload capability. The holster included removes the immediate need to source a secure carry option; this is especially valuable when a new owner needs to establish safe handling practices right away. The original box is also useful for transport and keeping paperwork together.

Handling, Ergonomics, and Training Considerations

The mid-size grip tends to fit a wide range of hand sizes, and the 509 platform is known for a consistent trigger reset and manageable recoil impulse. Even though the caliber is not specified in the listing, the 509 family commonly comes chambered in 9mm—confirm the exact chambering on the product page before purchase if ammunition type is important for your training plan. Until the caliber is confirmed, treat the pistol as optic-ready, holster-equipped, and magazine-ready as described in the listing.

Range Work and Carry Setup

When you pick up a used firearm listed in GOOD CONDITION, start with a careful function check and a slow live-fire session at the range using quality ammunition. Verify feed, extract, and ejection patterns, and spend time with the included holster to assess retention and draw smoothness. If you plan to run an MRD, ensure the sight footprint matches your chosen optic and that the holster accommodates the optic profile.

Buying Considerations and Price Context

At $575.99, this package-cost approach can represent savings compared to buying a like-kind optic-ready pistol plus holster and magazines separately. Confirm the seller photos and condition notes on the product page, and verify serial and transfer requirements for your jurisdiction.

FN 509 MIDSIZE MRD [BLK] in this listing gives you an optic-ready mid-size semi-auto with two magazines, an included holster, and the original box—an attractive combination for someone looking to enter the FN platform or add a versatile mid-size pistol to their collection. Always verify the exact model details and caliber on the product page, complete background and transfer requirements lawfully, and follow safe storage and handling practices once the firearm is in your possession.
