Well, it took a a long while. And it cost an awful lot. But was it worth the wait and the cost? Well, after due consideration I can only say, "Hell Yes"!!!
After placing my $2.5K pre-order back in December 2024, I patiently awaited the arrival of my SIG Legion Flux Raider PCC/PDW. After what seemed like an interminable wait, February 2025 finally rolled around and true to their word, Rangeview Sports received the "Canadianized" SIG P320 Flux Raider kits from M.D. Charleton, the SIG Distributor for Canada. In lieu of the Fire Control Unit (that cannot be transferred under the Canadian "Hangun Freeze"), and 2 x 10/30 Magazines, the Canadian SIG P320 Legion Flux Raider would ship as a parts kit substituting a custom 4.1" Barrel for the Canada-verboten 3.9" US Standard Legion Barrel length and 2 x standard-length 10-round Magazines for the 30-round factory Mags.
Given the relatively short length of the compensated SIG P320 Legion Slide, I had always planned to swap out the integrally-compensated Legion slide to my B+T P320 Folding Stock Chassis, and then take my longer, SIG P320 X5 Slide and Compensator and put it on the SIG Flux Raider Chassis. This swap would better balance both firearms in terms of matching up similarly long slides and Barrels with an equal-length Chassis. In the case of the P320 X5 Slide and Compensator, this longer assembly would project just past the end of the Raider Chassis instead of ending within the frame and looking out of place. Fitting the X5 Slide and Compensator to the Flux Raider Chassis took some Dremel and sandpaper work at the Muzzle end in order to accommodate the partially-recoiling Comp, however the end result was worth the effort and risk as I really like the look (and effect).
Additions to the basic SIG Legion Flux Raider parts kit include:
- Killer Innovations P320 X5 Threaded Bull Barrel
- Killer Innovations P320 X5 Compensator
- Tactical Development F10 Ambi Charging Handle
- Tactical Development Right Side Safety Delete
- Flux Defense 1.5" Length of Pull Buttstock
- Flux Defenxe Gen 1 Operating Lever with Slide Catch Detent
- Holosun AEMS Red Dot Carbine Sight
- Streamlight TLR-8 Light/Red Laser combination
- SIG 10/21-round (Front) and 10/30-round IRear) Magazines
In addition to the aforementioned Dremel and hand-sanding work on the Muzzle end of the Chassis, I also decided to remove approximately 2cm from the bottom tip of the Buttplate. I used a hacksaw to remove the bulk of the material, finishing and blending the cut polymer with additional hand-sanding. Sometimes perfection requires risks. This time it paid off in Spades! The tip of the Buttstock no longer projects below the line of the firearm and therefore doesn't catch on the zippered edges of my sling-bag during a hasty retrieval.
