CAPABLE PCC PLATFORM
SIG Sauer teamed up with Flux Defense, a Utah-based company that has been producing very popular PDW chassis for the last couple of years, to produce the P320-Flux Legion. The P320-Flux Legion encapsulates a SIG P320 Legion 9mm handgun in a rugged and highly capable Raider X chassis by Flux Defense. The result is a PCC-style platform that combines the maneuverability of a handgun and the stability of a carbine.
A spring-loaded adjustable brace pops out when you hit a lever on the right side. The release button is only on the right side, catering to right-handed shooters.
Flux Defense adds an ambidextrous manual safety to its platform, which is like that of a carbine and is within easy reach of either thumb. The chassis also has quick-detach M-LOK mounts that allow a sling to be quickly detached or attached. These guys have thought of everything.
OPTICS-READY
The P320-Flux Legion I received from SIG had a Romeo5 optic installed, but the small Picatinny rail accepts a wide variety of red dot sights. The optic does not reciprocate. There’s also a small gap under the rail that lets you use the gun’s iron sights as a backup.
Yes, the sight rides high atop the barrel, but for the shooting I did between 10 and 50 yards on torso-sized targets, the gun showed excellent accuracy. This is a close-quarters gun. You could adjust it to the exact range you intend to shoot, but right out of the box, the sight was on for the distances at which I was shooting.

RANGE TIME
Because this P320 is designed for close-range work, I will be engaging steel and 2-liter root beer bottles at 10 yards. One steel target will be placed at 20 yards to challenge me a bit. Today’s choice of ammo is PMC Bronze 115-grain FMJ.
Hits on steel are easy to keep centered. The Romeo5 red dot is in front of my eye and easy to place on any target. The slide moves quickly. I can feel the thump of the slide on each shot, but it does not affect my aim. The high-rise mount protects the sight from movement and vibration, and it’s easy to make headshots and shots to the steel flapper.
Now for some root beer rapid-fire! Targets are randomly placed from 10 to 15 yards. Starting from right to left, I shoot the 2-liter jugs as fast as I can. With few misses, I can hit anything that the red dot is placed on. Recoil is nearly zero, thanks in part to the ported slide expansion chamber.
Over 350 rounds of mainly 115-grain PMC FMJ, I haven’t had any issues. I did take it apart to clean and lubricate it once. Takedown is standard.
FAST RELOADS
Mag changes are about as fast as they come with the dual magazine release system and two included 30-round magazines. There are a few ambidextrous mag releases, and the one I like is at the rear of the backup mag. Press it lightly, and it drops the extra mag. Press it hard, and both mags drop.
Grab the forward magazine as it drops and replace the rear mag as it drops to the ground. No need to reach into a belt pouch for a spare magazine. It is in my hand immediately and loaded quickly. Amazingly fast!
The other two magazine releases are located on either side of the frame. The right-side release is behind the forward magazine housing like on an AR-15 platform, while the left-side release is a forward-sliding button above the pistol grip not unlike that of most semi-auto pistols. All the mag releases work well and can be learned quickly.
