FN 509 Midsize 9mm Blue/Black Pistol

A: Yes, they will fit however FN recommends using the spacers they sell to prevent overinsertion and potential damage. Inserting them carefully or at least without really slamming them in hard should be enough to avoid any issues.

A: Llewellyn, Yes the 17 round magazines will fit and function in this firearm.

A: Gerald, different manufacturer UPC codes mean two different configurations. The model above has Sights: FT: 1-Dot Luminescent RR: 2-Dot Luminescent and the 509MRD has All Black Co-Witness Height Sights. Cheers and stay safe!

A: MRD is optics ready (slide comes milled ready to accept resdot mounting plates), has night sights, and has 3-17 rd magazines. https://fnamerica.com/products/law-enforcement/fn-509-mrd/ ---------------- The other one is bot milled for a redot, has luminescent sights ( not true night sites they glow when charged by light) and 2-15 rd magazines.

A: This one has a standard slide and sights, the MDR has "FN Optics Mount System" basically just a cut slide for running an optic.

A: Yes this model is compatible with 15rd, 17rd and 24rd magazines, the bottom will hang down a bit but it will still function with no issues.

A: Juan, yes Sir. the 24rd Magazine is the same as the 15rd magazine that fits and locks into the magazine well. The 24rd magazine is just longer and holds more rounds. Cheers and stay safe!

A: Hi William, no sir, the gun must be paid in full before the rebate offer expires. Stay safe & have a great day!

A: What If a customer put it on layaway, received the rebate check before it was paid then canceled the layaway, they now would have a free rebate check. So that is a strong no, it would need to be paid for in full before being able to get the rebate & b4 it expires.

A: Hi William and welcome. No Sir. The rebate, if Dec. 31st, must be paid for and invoiced by the 31st and you have until Jan 31st to submit rebate application. Cheers and happy holidays!
