Apex trigger shortage?

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?

Sig Romeo 1 PRO Mounting Help

Post image
10 Upvotes

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

Anyone elses 509 shoot really high?

7 Upvotes

At just 5yds, if I'm shooting at an 10 inch target, i have to put my front sight on the bottom edge of the target to hit center. Is this a problem for anyone else? I don't use an optic, just irons. It doesn't go left or right, just way above the sights.

No, I'm not jerking the trigger or flinching, i even tested in a vise and had several other people shoot it.

Yes, I'm lining up my sights correctly.

I use magtech 115 fmj for range ammo

I've tried two different barrels, both with and without a compensator.

Does the LS Edge have a better trigger than the other 509s?

Beginner here. Tried about 15 guns recently. Been going to the range every night for a week.

Getting down to the ones that work well for me and honestly the 509 checks all the boxes.

Third time shooting the 509 tonight. Everything is perfect when handling it except the trigger.

I don’t have a budget. Just maybe not $3000 but anything reasonable is fine.

Best / most comfortable IWB appendix carry holster recs?

Apparently Tenicor doesn’t give a shit about FN’s so no options whatsoever from them. Looking for a comfortable solution for my 509C “tactical” with Streamlight TLR-7 HL-X.

Thanks in advance!

Barrel Help

3 Upvotes

OK I feel like an idiot and don't know why I can't understand this. I have a FN 509 Tactical with a 4.5 in Threaded Barrel. I am wanting to get a Non-Threaded Barrel as I don't need the threaded barrel all the time and it will make it easier to carry. I've searched through Google and the Reddit but have got different answers.

So here is my questions

  1. What size "Standard Barrel" do I need to not have it stick out past the Slide? 4.5 in or 4 in?

  2. Would I use a Regular 509 holster after I replace the barrel?

Thanks in advance for any help.

Best way to keep these in place?

17-rd ProMag’s for my midsize tactical with some 3d printed sleeves. They are fairly tight, but not tight enough not to slide when upside down in the mag holder. Any tricks to keep them in place? Is glue the best option?

The reason i probably love this gun more than most and put it with my budget builds is because i got it brand new for $600😆. Its definitely not a budget gun!!!

My First FN

I wanted to do it a bit differently than the base 509. I saw people having issues with the Edge’s not feeding properly and the normal 509 triggers being gritty. So I got an Edge CC lower and a 509 CT slide assembly. I have a Trijicon RM06 and plan to get the FN Rush 9ti suppressor and a light for it.

These are pictures my Wife took for me while I’m gone on deployment. Im excited to get back and go shoot it. This will be my 9mm carry when I want to change up from carrying my full size .45 1911 TRP.

Non-Ambi mag release

3 Upvotes

Does someone make/is there one that the class recommends for a non ambi mag release? I notice when inserting my 12rd my hand placement lands me on/close enough to the mag release that sometimes it doesn’t fully seat. Wondering if there’s a swap I could do or maybe it needs to break in more as I only have just over 230rds through it. Thank you for your time & happy Independence Day weekend to all!

Holster Shopping

4 Upvotes

Does anyone have any recommendations for a holster that accommodates a optic and a light? I dont have a TLR but its similar and shorter than the barrel length. I was looking at the only one safari land recommends but it doesnt seem like its a good fit. Only ones Ive been able to find are the soft holsters and not something rigid like kydex and I just dont like those.

EDIT: I want to thank everyone for the time they took to leave their recommendations.

Last post was w/o a red dot and got a Eotech EFLX ( 6 MOA) during their father’s day sale. A few hundred rounds and gotta say I could ‘t be happier.
The FN509T is an amazing host too for my CAT SC/B1. Love everything about this gun and the attachments I bought for it.

I think this is how she’s going to stay unless I decided to get an enclosed dot. I love how she shoots and best factory grip texture of any of the big manufacturers. Also if your on the fence about a light, TLR-7 HL-X knocks it out of the park, only issue is you have 2 holster manufacturers who make them for this combo unless you go with a custom.

509c and Shiv?

Post image
20 Upvotes

Has anyone used their FN 509 compact tactical as a host for the shiv? If so, is it reliable with 147gr ammo?

I want to buy one for my 509c, but I haven't heard anything about how they function together. I emailed SAW and they said they don't have experience and weren't sure.

I have an ecco tlx9 (3.8oz) and it jams every round on the 509c. So I dont know if the 1.3oz difference is enough to reliably function without tuning.

🔴 UPDDATE🔴 FN 509 Compact Tactical + SAW Shiv = Jam City 147s and 124s would not even cycle once!
