RAIDER 365 BLK PDW
Flux Defense Raider 365 BLK PDW Chassis — SIG P365 Platform
So you own a SIG P365 in the Czech Republic or Switzerland and want genuine PDW-level performance in a concealable package. This chassis delivers that. The Flux Defense Raider 365 BLK PDW — the world’s smallest PDW chassis system, designed specifically for the SIG Sauer P365. Not a firearm. Ships directly as an accessory component.
This RAIDER 365 BLK PDW is not a firearm — it is a chassis upgrade. First, the Raider 365 is a chassis upgrade that transforms your P365 into a compact, mission-ready PDW with unmatched speed and control. Next, it is made from 7075 Aluminum and S7 Steel, and allows the user to carry up to 50 rounds on the gun with optional mag extensions. Finally, installation is like any other P365 grip module — a single pin is all you need to push.
Available at eurogunandpartshub.com — supplying licensed handgun owners in Czech Republic, Switzerland, and other European jurisdictions where SIG P365 ownership is legally permitted.
Important legal notice: This product is sold exclusively to buyers in European jurisdictions where handgun ownership is legally permitted and where the addition of a chassis system does not create a prohibited weapon configuration under local law. Buyers are solely responsible for verifying legal ownership requirements in their country before purchasing. Always verify with your national firearms authority before ordering.
Is This RAIDER 365 BLK PDW Legal in My European Country?
Only in specific jurisdictions — verify before ordering. So the SIG P365 pistol is restricted or prohibited in the UK, Germany, France, Netherlands, and most European countries for civilian ownership. Also, Czech Republic and Switzerland have more accessible handgun licensing frameworks that permit civilian ownership of pistols including the P365 with appropriate licensing. Therefore, this chassis is sold exclusively to buyers in jurisdictions where both the SIG P365 and its modification with a chassis system are legally permitted — contact eurogunandpartshub.com before ordering to confirm your country’s requirements.
What Does This RAIDER 365 BLK PDW Actually Do to My P365?
It transforms a concealable pistol into a stable, accurate PDW platform. So the Raider 365 adds a quick-deploy stock for stability as well as doubling or more the ammunition capacity.Also, it gives your P365 three to four points of contact, MP5-like accuracy, and the ability to run a 6″ barrel — all while drawing as fast as a standard handgun. Therefore, you retain the concealment advantage of the P365 while gaining the stability and accuracy of a much larger platform.
What Are the Dimensions When Folded and Extended?
Genuinely RAIDER 365 BLK PDW smaller than most full-size handguns. So the short version measures 9.75 inches when folded and 18.5 inches extended.Also, despite having a 6″ barrel, the Raider 365 is nearly the same size as a Glock 17 with an X300 weapon light. Therefore, the folded profile is small enough for concealed carry in appropriate holsters the optional Two-For-One holster works both IWB and OWB.
What Does Independent Testing Show?
Real-world performance data from documented drills. So real-world performance includes 3.17 seconds on the Dicken Drill and 1.52 seconds on the Bill Drill from concealment. Also, the Raider 365 is faster, more accurate, and more controllable than a handgun alone in almost every metric — speed, control, capacity, and accuracy. Therefore, the performance claims are backed by documented drill times, not just manufacturer marketing.
What Accessories Work With This RAIDER 365 BLK PDW?
A growing ecosystem of compatible accessories. So the short version sits flush with a Streamlight TLR7sub, SureFire XR1, and Nightstick TCM-550XLS with approximately 2.5 inches of space to work with for weapon lights. Also, the chassis features many threaded mounting holes for third-party accessory developers, a forward optic mount in RMR and ACRO footprints, and a Dual Mag System that allows a spare magazine on the chassis body with a single-press drop for both magazines simultaneously. Therefore, you can build a complete, accessorised PDW setup around this chassis.
