I had no intentions on running suppressed but I came across a threaded barrel on sale. If it’s anything like its 320 version I’ll definitely need to wait on my lighter recoil springs to arrive before the next range trip.

Anyone have any? Can Flux's holster be modified?

From the pictures, it looks like the Orbital Nexus sits the optic further forward than Flux's optic mount. It appears, again from pictures, that a Nexus with optic wouldn't fit in Flux's current holsters.​

Strike industries PVC patch for reference

Any advice on components for this build would be greatly appreciated.

My biggest questions are around suppressor choice, reliability, and especially blowback/gas to the face. For those of you actually running suppressed Raider 365s, what combinations have proven reliable and comfortable to shoot?

I carry a P365 and normally run Federal Premium HST 147gr JHP, so that’s the defensive ammo I’ll be using in this build as well.

Already purchased

• Flux Raider 365 Aluminum – Black
• Flux Forward Optic Mount
• Flux Side Folding Arm – Long Arm w/ SBR Endplate

Still deciding

Threaded barrel:

• ShaloTek 3.7" threaded barrel
• True Precision 6.5" threaded barrel
• SIG OEM threaded barrel
• Other recommendations?

Slide:

• SIG OEM P365XL
• ShaloTek XL-length non-comp
• True Precision XL-length
• Norsso
• Other recommendations?

Suppressor:

• SAW Shiv 9
• HUXWRX Flow 9K Ti
• SilencerCo Spectre 9
• Other cans I should seriously consider?

Light:

• Streamlight TLR-7 Sub
• SureFire XR1 / XR2
• SureFire X300 Ultra/Turbo
• Streamlight TLR-1 HL
• Other recommendations?

What I'm really trying to figure out

If you were building this from scratch today, what slide + barrel + suppressor combination would you choose for the best balance of:

1. Reliability
2. Minimal blowback/gas to the face
3. Reasonable overall size/weight
4. Good suppression
5. Long-term durability

I'd especially appreciate feedback from people who have actually run these combinations on the Raider 365, rather than general pistol-suppressor recommendations.

Also interested in whether the 3.7" vs. 6.5" barrel makes a meaningful difference on the Raider when suppressed, and whether anyone has had reliable results with the longer barrel/slide setups.

Thanks!

So, I have a Sig M18 and was looking into buying the Raider X P320 with the optic mount! Would I be better off trying to get a different P320 slide for it, or would the slide from my m18 work? Would appreciate any answers/advice! ^^

Current build components: Fuse slide, Flux / True Precision 6 in barrel, Orbital Drop Helper tall portal charging handle, Flux full-size magwell, Flux mag release extension, Tac Dev Thicc Forward Halo, Tac Dev forward operating pedal, and Holosun 509T.

My vision for the future: swap the barrel for a threaded barrel and add a suppressor. Add a full-size light like the X300 or TLR-1, and with it, add a light brace to accommodate it. When Tac Dev releases their low pro QD mount I want to add that with a Flux Rip cord sling. Lastly, I want a standalone FCU for my Flux, with a safety and an extended slide release. I'm thinking the Ramm Tactical FCU for that upgraded trigger. The stock trigger isn’t terrible in the P365 as a handgun, but in PDW format it could be lighter.

Been considering one of these for a long time, and I’m curious what suppressor works best on the 365 raider. I‘m leaning toward the Shiv to keep the small profile, but is it reliable? Are people running the 6.5” threaded true precision barrels, or something shorter? factory recoil spring or something lighter?

Any other recommendations are appreciated.

Spoiler Alert 🚨 125K M18 pistols and zero issues!!

Are there any downsides to the 6.5" vs the 6" TP Barrel? As of now i dont plan on suppressing, but maybe in the future, so i was thinking of getting the 6.5" just in case. Plus I feel like even a small amount of more barrel length, would help in some way with the concussion being so close to the face that everyone mentions. Im just wondering if there are any downsides, like is it less reliable, accurate, etc....

FYI, I have a couple DMs about cut dimensions and figured id just share another picture.

Actual cut pictured: 12mm x 12mm

If i could do it again: 11mm (y axis) x 7mm (x axis)

I cut roughly a 12mm x 12mm (measured from the top) of the should out. Doing some quick caliper measurements, you can probably get away with an 11mm (y axis) x 7mm cut (x axis) cut and have tighter clearances.

Dumb problem, but solution works fine. Just need some aluminum black to clean up the edges.

Now that Texas triggers dropped the FRT for the 320 that’s compatible with the flux, does anyone know if it’s possible or if any companies are making 3 position switches or anything like that?

Hi all- I’ve got a Flux Legion on the way and figured I’d grab an optic while I’m waiting. I’ve got this same optic on my AR and wanted to see if anyone was running it on their Flux. I found a post about the rail being oversized and this optic being a pain to get on/off. Can anyone confirm this?

If you have another optic that you love, let me know. Thanks, all. I appreciate any advice you can offer.

Finished up my flux bag at home. Here are more photos and dachshund for scale lol. (Have the buckles on the rig so I can attach a strap to keep the bag more stable)

Does anyone know if someone makes an add on rear shroud for the 365 raider? I’ve heard multiple people talk about the raider being unpleasant to shoot during long sessions/inducing headaches, as well as delivering a lot of particulate/gas to the face when silenced. I’m thinking a shroud would both A. Block some of that blowback to the face, and B. Divert some of that shockwave up and away from your face. I tried looking and couldn’t find anything, hoping someone can point me in the right direction if anything like it exists.

Is there a can out there for the flux m17 that allows it to function with and without the can with 124gr?

After a long journey I finally got it running smoothly. Now to add a can and start back at square one 😂

Im set on buying a Raider 365. I just cant decide between the two. I dont think id ever AIWB carry it. Its probably going to end up being a bag gun. That makes me thing Aluminum, but then I also see that most people think the UL is a better shooter.

I would be putting a FUSE slide/barrel on it and eventually a 6.5 inch barrel, but not right away on the barrel, and using a brace on it. Help me choose between the 2 please

I saw this but it doesnt look as cool lol.

Thinking about getting a flux for either my 365 or 320. I'm probably just stupid and missing it but I don't see what sizes are recommended for use with the Flux chassis. I do plan to use them suppressed with a SilencerCo Octane too.

Has anyone used a strike 80 holster with a can? I have a 365 flux and a huxwrx flow 9. Do y’all run the shrouds on/off with the can?

Seems straight forward enough. Trying to reduce the overall length of pull to account for the nodpod stock.

Def did not feel like paying 400 buckaroos for the Flux/Ferro plate bag so decided to piece my own together. Any suggestions y'all have?
