FN Car Mount Guide: 509 MRD, 509 TAC, Reflex, 503, FNS 9C, FNX 45
FN car mount guide: magnetic, model-specific mounts for the FN 509 MRD, 509 TAC, Reflex, 503, FNS 9C, FNX 45, FNP 9 and FNH 57. Check your model first.
FN builds pistols for militaries and police departments, and plenty of civilian owners keep one in the truck. The trouble is that FN’s lineup runs from the pocket-size Reflex to the full-size FNX 45, with several 509 variants in between. An FN car mount only works well when it is built for the exact model you carry.
Below are the eight FN models At The Ready makes mounts for, followed by how the mount holds, whether to pick optic-ready, where to put it and how to install it without drilling.
Key takeaways
- At The Ready makes a separate magnetic mount for the FN 509 MRD, 509 TAC, Reflex, 503, FNS 9C, FNX 45, FNP 9 and FNH 57.
- The 509 MRD and 509 TAC are two different mounts, so check the model marked on your pistol.
- Every FN mount is $95 standard or $105 optic-ready.
- Screws, VHB tape and primer come in the box; in a vehicle, use the screws or the tape with primer.
The FN Lineup, Model by Model
FN America lists its current pistols on its official site. Each At The Ready mount below is designed from that model’s actual slide:
| Your pistol | At The Ready mount | Standard | Optic-ready |
|---|---|---|---|
| FN 509 MRD | 509 MRD mount | $95 | $105 |
| FN 509 TAC | 509 TAC mount | $95 | $105 |
| FN Reflex | Reflex mount | $95 | $105 |
| FN 503 | 503 mount | $95 | $105 |
| FN FNS 9C | FNS 9C mount | $95 | $105 |
| FN FNX 45 | FNX 45 mount | $95 | $105 |
| FN FNP 9 | FNP 9 mount | $95 | $105 |
| FN FNH 57 | FNH 57 mount | $95 | $105 |
The 509 family is where most mix-ups happen: the 509 MRD and the 509 TAC each have their own mount. Read the model on the slide or frame before you order. If your FN is not in the table, or the marking does not match a name here, call At The Ready at (469) 304-8535. All FN mounts are on one page.
How the Mount Holds an FN
There is no choosing between a magnet and a shaped holder here, because each mount is both. Rare-earth magnets sit inside a premium ABS body that is molded to one FN model’s slide. Set the pistol in and it seats in the same position every time, grip toward you, and it stays put over washboard roads and hard stops.
The trigger guard stays open, so the usual rule applies: finger off the trigger until you are ready to fire. If your FN wears a weapon light or another rail accessory, ask At The Ready about clearance before you order.
Should You Pick Optic-Ready?
The 509 MRD and 509 TAC are built for red dots, and many Reflex owners add a small optic too. If a dot is on your pistol now, or you plan to add one, choose “Optic: Yes” for the optic-ready mount at $10 more. The FNX 45, FNP 9 and FNH 57 are often run with iron sights, where the standard mount is the common pick.
Optic-ready by itself does not confirm clearance for a light or other accessory. The optic-ready gun mount guide explains what the option changes.
Picking a Spot in Your Vehicle
Most drivers put the mount on the side of the center console, where the grip lands near the right hand. In cars with a narrow console, the lower dash works better. A full-size FNX 45 needs more room than a Reflex, so sit in your normal driving position, hold the empty pistol where the mount would go and take a full grip before you commit. Keep clear of the knee airbag and the pedals.
The car gun mount guide compares placements in sedans and SUVs, and the truck gun mount placement guide covers pickups. If the grip crowds your knee, the angled mount adapter ($14.99) tips it away.
No-Drill Installation
Every mount ships with screws, VHB tape and primer. In a vehicle, use the screws, or use the tape after wiping the surface with the primer. Tape alone is not enough on textured interior plastic. The no-drill gun mount guide walks through the tape method, and the installation page has a short video.
Make It Yours
Black is the standard base color. Twenty-five colors are included, along with up to 18 characters of custom text, such as a name or unit. Each mount is made in Wylie, Texas, by a veteran-owned company and is covered by a lifetime warranty.
Safety and the Law
A mount is for quick access, not storage. It does not lock, so take the pistol with you or secure it when you leave the vehicle. Practice drawing with an unloaded pistol until it is smooth, and learn the vehicle carry rules for every state on your route.
