There is a thread in here with 509T holsters. I made
a post in there about running the 509T and X300U in a Safariland 6390-RDSAnother option is the
TREX Ragnarok SD Type 2 if you want to run a suppressor as well.
Here iis my post below:

I can confirm this as well. Below is a 6390RDS-4502 holster meant for a Sig P320 RX with 4.7" barrel. My 509T with RMR and X300U fits in it well. After a couple dozen times taking it in and out it has worn into the gun and is much smoother
I still plan on buying a 509T specific holster when they make them for the 6390RDS line, but until then, this will work perfectly for practice and classes.

Alright, I'm back with an update.
Long story short: If you want a 6390RDS for your 509T with light and dot, get the 6390RDS-2702 for the 509 model and remove the barrel plug.Back in June I ended up ordering a 6390RDS for the FN 509 (note, they don't have a drop down for the 509 T yet).
The model number was 6390RDS-2702 and I ordered it for an X300U and RMR in FDE. Full code on my holster package is "6390RDS FN 509 X300U STX TAC FDE RH"
The first thing to note is as expected, the longer barrel of the 509T does not fit in the holster. I removed the barrel plug with one bolt and then spread the holster to get it out easily. Once the barrel plug is removed then the 509T can easily fit in this holster, and it fits GREAT.
First image below shows the barrel plug removed. Once you holster the gun and adjust the tension screw, it is incredibly secure. I'm not worried about retention with the lack of barrel plug.
Next photo of the Tan holster is the 509 specific one. Followed by the black holster is the one I was previously using that is made for the P320 / M17. You can see the 509 holster is much slimmer and more fit to the gun. Very happy with the swap.
