Built on the compact SIG P365 9mm platform, this example is outfitted in a Flux Defense P365-pattern chassis that adds a rapid-deploy rear arm and a forward spare-magazine carrier. The chassis integrates an under-barrel accessory rail and features textured contact surfaces. The frame is polymer, and the slide is optics cut.
Barrel options are a highlight of this setup. It includes the factory 6-inch barrel with a matching shroud (installed), plus a packaged Ballistic Advantage P365 XL 3.7-inch 9mm threaded barrel (1/2x28). The chamber hood is marked "9mm x 19," and the barrel material is alloy steel.
Target acquisition and illumination come from the installed slide-mounted micro red dot sight and the Streamlight TLR-7 X Sub. The Antimatter Industries Wing on the light is installed to complement the control setup. The slide’s optics cut supports the reflex sight configuration already in place.
Capacity is listed at 25+1, and the sale includes five OEM SIG P320-pattern extended magazines: two 17-round, two 21-round, and one 25-round. The chassis’ integral forward carrier provides an on-board spare-mag solution. Origin is USA, with the frame molded "NEWINGTON, NH USA."
