The Flux Defense Raider Magwell (Flux Defense part no. 165-00023) is a flared magazine well built for the full-size Sig Sauer P365 platform, designed to funnel a magazine into the grip faster and more reliably during a reload. Flux Defense engineered the Raider to widen the grip’s opening without adding excessive bulk, so the pistol still conceals and handles like a stock P365 between reloads. Faster, more consistent reloads matter for competition shooters and anyone training seriously for defensive use. It is a focused upgrade for full-size P365 owners who want to shave time off every magazine change.
