The Maxim Defense PDX 505-SPS builds upon a foundation of proven operational reliability, integrating the advanced SCW Pistol System to optimize its compact form factor. This iteration retains the inherent robust performance characteristics while specifically addressing requirements for a highly streamlined pistol configuration. The SCW Pistol System is engineered to reduce the firearm’s overall profile, mitigating snag points and enhancing operational fluidity in confined environments.
Key Features
Optimized SCW Pistol System
The defining characteristic of the PDX 505-SPS is the integration of Maxim Defense’s SCW Pistol System. This proprietary system is engineered for maximal compactness, presenting the most streamlined rear interface for an AR Pistol. Its design eliminates protruding angles, preventing snags and facilitating rapid deployment. Weighing a mere 5.3 ounces, the SCW Pistol System contributes to a significant weight reduction, trimming over 10 ounces compared to the SCW Stock variant. This mass reduction directly translates to enhanced handling dynamics and reduced operator fatigue during extended use.
Integrated Sling Point
The SCW Pistol System incorporates a rear single-point QD (Quick Detach) swivel mount. This strategic placement supports the use of a sling to facilitate stable shot placement and optimize weapon retention during dynamic movement or transitioning between targets.
Compact & Durable Construction
Designed for professional-grade utility, the PDX 505-SPS maintains a compact footprint with its 5.50″ barrel. The firearm features an Urban Grey metal finish for enhanced durability and corrosion resistance, complemented by an Urban Grey polymer grip engineered for positive purchase and ergonomic control, even in austere conditions.
