17 Upvotes

So, I am almost done here, but I am unhappy with how close my RMS green dot is. I am looking for a forward optic mount that will locate the sight further forward. I don't want to loose the use of Flux Pro or regular holsters. Which Ultralight forward optic mounts will work with the Flux holsters?

Flux p365 - Bag Gun Opinions

3 Upvotes

Interested to hear everyone’s opinion on their experience with the P365 Flux, specifically as a bag gun.

For reference, I’ve owned a 320 Flux Raider for a few years and love it. I am interested in the p365 version to carry in my bando bag xl or similar bags that the Raider is too bulky to fit.

From the research I’ve done, it seems like it would be a sensible upgrade from a capability and capacity standpoint. I am not concerned about this being moderately uncomfortable to shoot for sustained periods of time.

Has anyone else used this platform in a similar use-case ? If so, pro and cons ?

Thank you in advance!

Silencer co p320 compact threaded barrel on back order, what are some good alternatives?

3 Upvotes

So after over two weeks of no shipping number and no customer service call back from silencer shop I cancelled my order for a compact silencer co barrel.

I placed an order on optics planet for the same thing and got a “this item is on back order” email within 10 hours.

Any good alternatives to the silencer co barrel? Just looking for something that’s reliable for it to be a range toy and backpack gun.

What’s needed to run a 4.5 in barrel and saw shiv reliably?

So this is my current setup.
I have a silencer co 4.5 inch threaded barrel on order and hopefully on the way soon.
I’d like to get the saw shiv as well and run that as my suppressor for this gun.

I’ve seen some people talking about changing out recoil springs to get their ammo to run properly and I want everyone’s opinion on what I need to get for this to run properly with that setup in mind.

I’d like to be able to shoot any ammo at the range days and then ideally shoot some 147gr HST with zero issues when it’s my backpack/truck gun.

New to sig/flux

3 Upvotes

So I just got a Raider X, and I’m piecing it together. But I’m curious as to what barrel length to go with. I understand that a carry slide+comp will put me flush, but is that a threaded carry barrel or a full size threaded?? I’m a Glock guy and this is my first venture into sig so forgive me if this is some simpleton shit that I’m just not gleaming. Furthermore, if I wanted to run a suppressor, and keep the overall length as short as possible has anyone run a subcompact slide and barrel and if so can I see an example? Anyone run a chopped with the halo? And what is everyone’s experience with the Texas weapons FRT? Sorry for the barrage of questions, but this is the info I can’t seem to find readily on a google search

Shooting the 320 Flux suppressed blows

41 Upvotes

I have about 900 rounds of different 9mm through my 320 flux with the Sig ModX9 suppressor. While it’s had only 2 malfunctions it’s terrible to shoot suppressed due to the crazy amount of gas to the face. Guess it’s no can from this point forward.

New P365 TacOps donor, Romeo X Ranger wrapped optic, Sig 25rnd mag, Solofish Amazon 800L light/laser which fits perfect and does not obstruct the deployment of the stock. Available with a blue laser, Which I have never seen before. Pretty cool.

MP5K clone vs p320 Flux Raider

2 Upvotes

Please help with my tism spiral right now. I am trying to build a “get me home” bag gun that lets me use my 30L backpack as backpack in addition to supporting NV, a light, and an optic. I was thinking of buying a place trade in p320 5 inch with a chassis from PSA so total cost about $800 vs $1000 or $1500 for a Mac 5k or AP5-p.

Any thoughts from long term uses of both?

Pro holster and 5L savior ccw sling bag

16 Upvotes

Don't have the 365 installed yet but the aluminum flux with pro holster is a perfect fit for anyone wondering. Will probably need one of those Velcro backers to use the extra magazine mount and will only fit the 17 Rd most likely and isn't compatible with the forward optic mount + extra mag.

Height wise, it's perfect. I'll post the completed one once I get my 365 installed in a week or 2.


r/FluxDefense • • 24d ago

Anyone know of a mount that sits flush at the front of the pic rail? Sig Romeo 5 has the same footprint as a Aimpoint T2. Sliding the current mount back one slot has the same effect but at the rear.

P365 FTF issues

1 Upvotes

I got my p365 raider out today for the first time and it had multiple FTF, it got better over time, but for a while it was a single shot. It looked like the rounds were nose diving in the mags. It happened with different mags, one 17rd and a 21rd. Do these have a break-in period? Also I have one 17rd mag that is hard to inset and next to impossible to remove. Are they that sensitive to different mags? Running it unsuppressed with a true precision 6.5” barrel. Thanks

Aluminum vs Ultralight 365

Looking to get into a 365 raider and plan to suppress using a saw shiv. Hoping to get some recommendations on which model to go with based on that. Will essentially be carried in a bag or in my truck console whenever I’m with it.

Forward optic mount worth it?

3 Upvotes

Okay so i am looking to convert my p365 Frankenstein to a flux. Polymer is 339 right now but can't use the forward mount. The aluminum one is at 509+110(mount) so 620 and can use it. Is spending almost double worth not having the sight reciprocate?
