Flux Defense Raider X PDW Grip – Sig P320

The Flux Defense Raider X is a PDW-style grip chassis (brand part no. 161-00035) engineered around the Sig Sauer P320 rather than the smaller P365 platform. Like the rest of the Raider line, it’s machined from aluminum for a rigid, precise foundation and includes a folding brace arm so the P320 can be shouldered like a personal defense weapon when the situation calls for it. Competition shooters and home defenders alike use this chassis to add stability to a duty-size pistol without switching platforms entirely. It bolts on in place of the factory P320 grip module.

Key Specifications

• Precision-machined from aircraft aluminum for a rigid, low-flex chassis body.
• Purpose-built for the Sig Sauer P320 platform rather than the smaller P365 frame.
• Includes a folding side arm that deploys the brace to a shouldered, PDW-style firing position.
• Hard-coat anodized finish with corrosion-resistant hardware for reliable outdoor use.
• Retains full compatibility with factory P320 fire control and magazines, requiring no internal modification.
