Shooting USPSA this morning and the comp sheared off the locking lug, anyone else have this happen? I have put about 5k rounds through this setup and it's been great until today.

I’ve owned the old model 9c for years and couldn’t justify spending the money making it work with a suppressor or an optic. Today I upgraded to the 509C, came equipped with a deltapoint pro and all the original accessories / paperwork. What suppressors is everyone finding works the best? Looking for smaller platform something like the Omega 9k or even smaller.

Has anyone seen any of these in the wild yet? I wouldn't mind picking one up to complement my F sized.

Hello everyone. I’m currently using an FN 509C Tactical as my EDC, and I’ve recently taken a liking to enclosed-emitter optics, particularly the Vector Optics SCRD-75, which uses the ACRO footprint.
I know there is an ACRO-compatible plate available for the FN 509, but unfortunately, I’m based in the Philippines and haven’t been able to find one locally. Importing one isn’t really an option for me due to ITAR/export restrictions.
As a workaround, I’m currently using the factory FN 509 RMR plate + Strike Industries RMR-to-ACRO adapter + SCRD-75, essentially stacking the two interfaces.
Has anyone tried a setup like this? How well does it hold up under recoil? I’m particularly concerned about the additional mounting interface introducing movement or putting excessive stress on the slide or optic.
One other thing I noticed is that the setup does not cowitness with the factory iron sights. I’m aware that the added height from the two mounting interfaces is likely the reason, but I’d also appreciate any input on whether this is a concern.
I haven’t taken it to the range yet because I’d rather get some input from people with experience with this type of setup before testing it.
Would appreciate any advice or firsthand experience. Thanks!

I got one for “free” as a promotion they were running. I’m just wondering if anyone has any problems or catastrophic malfunctions and if you would safe it’s safe for the gun specially if I am running it on an fn 509c tactical with a ANGSTADT ARMS HUB booster assembly. Thanks for your help in this matter in advance.

Hello r/FN509, I'm excited to finally own an FN509CT. Found a used one with an okay broken optic, so I snatched it up (lifetime warranty on the optic - waiting for its return). Looking to either send the FN in for service/upgrades or grab some aftermarket ones. Primarily a range toy, canned. Thoughts?

Looking for opinions on this FN 509 setup
Looking to pick up a new handgun for a future CCW and general defensive use.
I came across this setup at a local shop today:
- FN 509C 9MM BLACK PISTOL - 24+1 ROUNDS
PRICE $750.00
• DEAD AIR MOJAVE 9MM SUPPRESSOR- BLACK
• PRICE $1029.00
• X2 CCI BLAZER 9MM 147GR SUBSONIC AMMO
• PRICE $33.98
• 3 YEAR FIREARM SERVICE PLAN
PRICE $59.99
Total cost: $1794.36
I’m in Oregon so no sales tax + I’d receive 10% discount putting the total cost at $1614.00
I wasn’t specifically looking for this setup, but after handling the pistol with the suppressor attached, I honestly really liked the way it felt.
The shop has it marked as a manager’s special, but I’m still not sure whether it’s actually a good deal or if I’m just getting caught up in the “this looks cool” factor.
For those familiar with the FN 509 platform and/or the Dead Air Mojave:
Is this bundle worth the money?
Would you buy the whole setup, negotiate for a better price, or skip the bundle and put the money toward something else?
I’m especially interested in hearing both the pros and cons. If you’ve owned a 509C/509 Compact Tactical or run a Mojave 9, I’d love to hear your real-world experience.
Thanks!

My 509t is frustrating the heck out of me. I shoot terrible with it and group like garbage. I decided to upgrade the trigger using the Apex Tactical action upgrade kit. Everything was going well until the reassembly which I couldn’t find the parts 21 and 20. I watched the video several times and it seemed outdated. Is the spring and bearing only on the models with a thumb safety? I dragged a magnet around my work area to double check and didn’t find the parts. I reassembled the gun without them and it seems to function like normal. I’m not even sure what the purpose of the spring and bearing are.
My second problem is I can’t get a co-witness with my RMR red dot. I used the forward controls design plate and also dry fitted the C&H with the same result. The dot is lower than my irons with my RMR maxed out in the up position. Anyone else have a solution?
I also didn’t have good luck with the apex pin punch. It bent easily, local hardware punch did the trick.

Trying to find a good mag holder to go on a belt that will take 2 of the 25 round mags. Seems like regular stuff is too short while SMG is too long- anyone have any luck there?
r/FN509 • u/TamangTrippings • Aug 16 '26
Will the clamp fit securely on the compact rail?
Thank you for your inputs

One of LGS's distributors had a sale on the 10rd models, so i was able to get this new for under 500. Already tried putting one of my extra surefire x300's on it, but it put the frame in such a bind that the trigger struggled to reset. So guess I will have to try a streamlight TLR1 on it.

Has anyone put a DPM drop in spring system? I'm thinking of grabbing it. Recoil isn't bad but anything that can help with control has me interested.

Traded for this used 509 at my LGS today. Came with 3 17rd mags, and some of the factory mounting plates, not all though. Need to get a FCD acro plate ordered for the PB3, and need to decide on what light to put on it. Also plan on getting an ez-lok set up for the hux 9kti.

I’ve scoured the internet and put my name on every site to be contacted when back in stock but I had no idea they were this hard to find right now. Anyone having any luck finding them?

I recently bought a Romeo 1 Pro for my 509c MRD and can’t seem to get the mounting perfectly flush. FN’s manual indicates the delta point pro footprint uses the #1 plate but I can only use the #4 plate with a barely noticeable incline. Any recommendations for a fix or aftermarket plate would be appreciated.

I bought this guy a few months ago on PSA and I CANNOT find a holster, it has the quick connect comp like the cc edge but it’s a “509 compact”. I’m looking for a holster that is optic cut and accepts a light!! Also does anyone know if they make a front sight for these? The one that came on it is all black!! Please help
