New ultralight. Is this excessive wear or normal?

I just received and assembled a new raider 365 ultralight. I have only deployed the arm about a dozen times at most and I’m noticing a significant amount of wear at the point where the spring engages the arm. I’m trying to figure out if this is expected or excessive for new unit.

Anyone Using Aftermarket Trigger P320 Flux Raider

1 Upvotes

I'm curious what aftermarket trigger setups people have had success with in a P320 Flux Raider. Is anyone running a trigger upgrade? Any reliability issues?

I've heard that some trigger shoes or trigger kits can cause fitment or reset issues because of the Raider chassis and its safety, while others seem to work fine.

I have a P320 with a Sig Armorer CORE kit and it greatly improved the trigger, but I use it with an adjustable trigger which Flux says they don't recommend. The flat trigger on my FCU leaves a lot to be desired.

I have the Palmetto Leather Works shoulder rig, and I was wondering what my mag loadout should be. I was thinking 17+17 in the flux and 21+21 in the mag pouches.

I got the 15rd magazines that came with the pistol, they don’t fit in the grip, is it a compatibility issue?

Suppressor Recommendation- Gas

The main concern I have is avoiding gas to the face. I already have a gas cap installed. Which suppressor do you guys have that has the least gas to the face? I’m leaning towards the SAW Shiv

Planning Platform Swap - p365xl and FUSE Tacops and Flux

1 Upvotes

Hey everyone, been lurking for a while wanted to throw out my game plan and see what advice I get from people. I have nothing for p365 at this time, recently sold all my spare glocks. I have a g19 for tactical competitions, and a hk cc9 for edc. I prefer on body, I also carry a laptop bag that fits a flux everyday all day, fits my style so no worries.

I want to pick up:

P365 XL w Manual Safety

P365 Fuse Tacops

Flux Raider Aluminum Chassis

Forward Optic Mount

RMR Footprint Holosun

I would run:

Run the P365XL AIWB as on body and can utilize the larger magazines.

Run the Fuse Tacops Slide, threaded, w Suppressor, x300 and forward mounted RMR footprint.

This gives me:

Flux setup that does forward optic and suppressed, Fullsize complete firearm, EDC complete firearm. The least amount of wasted parts or additional parts buying the poly chassis ready to go and I have to then get a threaded barrel and no forward mount.

Thoughts:

Or do I go with no forward optic?

I know fuse slide is a little thicker, plan on being suppressed and not running the shroud ever.

Compensator compatibility

Hey so I have a p320 carry and got an Sig threaded barrel (I believe it is the 4.6 variant) it looks a bit long however, will the The Herrington Arms HC320R Compensator fit well/ fill it in to the end of the flux raider chassis?

Would this be a decent upgrade for my p320 flux legion?

Heck of a deal at 150 vs 400. Currently just have a fast fire 3 on it and it's just too small for my liking. But a romeo 5 gen 2 would probably be a tad too big.

One of the more fun guns that I own. I was hesitant to get a flux for a while, this was a why not purchase. Easily became one of my favorites to shoot!

Just picked up a 320 el camino - best charging handle?

3 Upvotes

I am building a Flux Raider chop top that my elderly mom can use (she lives on remote property). I chose the el Camino so that I can put a big easy to use charging handle on it. I plan to mount an optic on a front mount.

https://fluxdefense.com/shop/raider-x-chop-top-el-camino

The gun will never be concealed. This is just for home defense.

So what’s the biggest easiest to use charging handle for the 320? Preferably one that mounts on the back.

Not sure what that spark out the back of the slide was. Any ideas? It only happened after the first round and never happened again so I kept going. As much as I love this thing I like my face more.

EPS vs EPS Carry on 365 UL?

1 Upvotes

I’m building a Raider 365 Ultralight with a P365 Fuse slide and 6” barrel. This will primarily be a bag gun carried in the Flux holster.

I’m trying to decide for the slide mounted optic between the EPS and EPS Carry.

Does anyone know:

-Does the shroud block the window of the EPS carry enough that you’d recommend the larger EPS?
-Does the EPS Carry feel too small so close to your face?
-Is the larger window of the EPS worth it?

I’m leaning towards the EPS Carry just wanted to hear some thoughts on it. Thanks in advance for any info!

Anyone else’s magwell just sheer itself off even though the bolt itself never came loose?

It’s got a little over 1k through it now. But I did make sure it was fit snuggly and not loose at all it kind of just started to droop through the latest range session. I applied locktite when it was originally installed as well. Kind of a bummer but nothing I can really do about it now.

Flux p365 Raider + custom Norsso slide + Shiv supressor

Post image
41 Upvotes

Was having some reliability issues once I threw on the SAW Shiv supressor. Changed to a lighter recoil spring and ran a bunch of boxes of 147 grain and it started to run more reliably. Still want to run atleast 200 more rounds and make sure its running flawlessly but overall happy with the set up!

I plan on making it an SBR at some point with the longer arm and bigger light so it aligns more with the supressor but for now its a perfect little bag gun.

Flux 365 Accessories question

2 Upvotes

I have some questions for those that have the Aluminum version of the 365.

For those that went the SBR route and got the longer arm is the extra 1.4" worth it? Or is it the endplate that makes it worth it? Or would you just keep pistol arm?

Is the forward optics mount worth it and how does it compare to slide mounted?

I currently run the 365 UL with Shiv but cant get either of these options of course so I have been thinking of buying the Aluminum ver to see if I could get slightly more comfortable behind the gun.

Also would you go Aluminum 365 or just get a 320? I was thinking 365 but don't know if its worth trying if I already have a UL. Main purpose of this would be backpack/range toy. UL currently is range toy/attempting to make it in the CCW rotation lol.

Thanks!
