Are you looking for the best concealed carry holster on the market?  Well, the search is over, because at Muddy River Tactical our Inside the Waistband Kydex Holsters are our best sellers!  Our holsters are handcrafted in the USA by hard working American Workers!  Your FN 509 IWB Kydex Holster will be custom molded to your exact firearm.  This guarantees a holster that fits and secures your firearm perfectly!  Furthermore, by custom molded to our exact specifications of your firearm, you get a holster that is thin and comfortable!  The custom fit will give you the perfect retention on your firearm to keep it fully secure.  All while maintaining a easy and smooth draw.  Some addition features of this FN 509 IWB Kydex Holster include:


FN 509 Holster – IWB Kydex Holster Features:

.  Adjustable Retention allows you to set your holster exactly how you like it!

.  Fully Adjustable Cant Angle from 0-15 degrees.  Everyone likes to carry in different positions and angles, so with our adjustable cant angle you can carry anyway from appendix carry to 4-5 o’clock with the same holster.  To adjust the cant angle you simply loosen the two screws holding the belt clip on, move the belt clip to desired angle, then tighten the two screws back up.

.  If you need to take off your firearm , you can have your holster off in a fews seconds.  There is no need to undo your pants or belt, you can simply slide these holster on and off.  Also because of the constant retention, your firearm will be secure whether you are wearing the holster or not!

.  We only use top quality .80 kydex to ensure a holster that will last a lifetime.  This kydex thickness provides a sturdy holster that will not collapse, for easy re-holstering.  However, it is thin enough that you do not sacrifice comfort or add bulk to your FN 509 IWB Kydex Holster.

.  Our FN 509 Holster comes standard with a FULL sweat shield.  A full sweat shield protects your body from the firearm for comfort.  It also protects your firearms finish from sweat and skin oils.  Another huge benefit of a full sweat shield is that it makes re-holstering your firearm way easier without the worry of pinching your skin.

.  These holsters only weight a couple ounces, so they add no weight or bulk to your concealed carry set-up!

More options

.  You have two belt clip options when you order your FN 509 Holster.  The standard clip is included in the price of the holster and fits belts up to 1.5″.  If you choose to upgrade to a tuckable belt clip, you gain the ability to tuck your shirt in to conceal your firearm.  The tuckable belt clips will fit belts up to 1.75″.  (The holsters are molded differently for each belt clip style, so if you order the tuckable clip you don’t get the standard clip option and vice versa)

.  All of our kydex holsters come with the option to add a claw attachment.  The claw is designed to ride against your belt and push the grip of the firearm into your body.  This eliminates printing and makes concealing your mid to full size firearms much easier!

.  We have over 40 color options to allow you to give your FN 509 Holster a custom look just right for YOU!

  6. Ryan H. (verified owner)

    The FN509 holster is not very popular so I was glad to find this company for mine. Fast shipping and looking over the holster great quality at this price range. Clean edges and fits my pistol perfectly and secure. I have the 509M (midsize) and works great for it.

  7. Guy (verified owner)

    Ships fast and sits comfortably.

  8. Daniel (verified owner)

    Great product, my 509 hasn’t touched anything else.

  9. Joe W. (verified owner)

    Ordered on Thursday and it arrived on Saturday. Shocked by the quick turnaround, I thought it would be a one size fits most thing. The holster fit my FN 509M like a glove. Quality product with fast delivery for an affordable price. I’ve already ordered another one for a FNS9C and the results were the same as above!

  10. Thomas Simon (verified owner)

    Best holster I’ve ever purchased online at this price ????????

  12. Eric S. (verified owner)

    Really great to order from them. Got it quick and it a great holster.

  13. ronald christian (verified owner)

    Overall, a very high-quality item. Very good attention to detail. Just a few asides: I bought this for an FN 509C Tactical. I understood it was a general fit holster for the 509 series. I am not faulting Muddy River for a holster that was a bit long for my handgun. I received it in about a week. That is worth not getting one that fit my sub-species of handgun perfectly. I simply cut it down and sanded it a bit to make a custom fit. That was very easy and took about 15 minutes.
    What I would respectfully suggest to Muddy River is that they could have done that even more efficiently at their shop and charged me a little extra for it, which I would have paid.
    My only criticism of the holster is that it left a little too much material around the trigger guard, thus making an instant proper grip with the strong hand a bit problematic. However, I have a lot of holsters, and this Muddy River is easily among the best. None of them is perfect.

    • MuddyRiver (store manager)

    I had to make some modifications to the tip of the holster so the pistol would fit with a compensator but that isn’t your fault.

  24. Eric Benton (verified owner)

    Perfect fit for my FN 509 Tactical. Patiently waiting for a TLR8 mold as well. Thanks!

  25. Josh M.

    Excellent conceal holster. I got the iwb tactical version. Came just under a week after ordering and was everything I expected. I would have liked a sticker from your company. Not that I’m complaining. Just would be a nice patch on my ammo can.

    Great holster, I’m new to the iwb holsters and heard they can be pretty rough especially if you’re new to them. The holster I got here is really comfortable and has no rubbing, in re even slept with it on. It’s a great comfortable holster and will be buying an owb holster from muddy river soon!

  46. Gregory M. (verified owner)

    Owner called morning after I placed online order to personally tell me the reason why they could not build a holster, which included a space for my Surefire X300 light…attached to my FN 509 Tactical.

    Appreciated greatly owner’s response and explanation. Everything else was ‘as ordered’ and shipping was better than expected.

    Will do business again with Muddy River Tactical!

  47. Kris Colvin (verified owner)

    Even though I don’t carry appendix because I’m a big man with big belly the claw attachment secures the gun to my back at the 4 and 5 o’clock position perfectly to where I do not need to worry with printing. The holster is comfortable and I do wear undershirts. Retention is great so I believe I will have more of these holsters for my other guns.

  48. Raymond trinidad (verified owner)
