Maxim Defense 505-SPS: Compact Semi Auto with Lightweight SCW Pistol System

Compact semi-autos that balance reliability, weight savings, and clean ergonomics are essential for professionals and responsible owners who want a capable defensive platform without excess bulk. The right back-end solution can transform handling, concealability, and sling performance while preserving the core reliability of the host firearm.

MAXIM DEFENSE PDX 505-SPS is the updated compact offering that keeps the same reliability-enhancing technology you expect while swapping in Maxim’s SCW Pistol System instead of the SCW stock or brace. The SCW Pistol System is designed as the most streamlined option for the back end of an AR pistol: no protruding angles and nothing to get caught on during movement or transitions.

Key design features and why they matter

The SCW Pistol System on this model weighs just 5.3 ounces, shaving more than 10 ounces off compared to Maxim’s SCW Stock. That weight reduction improves balance and reduces fatigue during extended carry. Its streamlined profile eliminates protruding angles—critical for avoiding snags on gear or clothing and for retaining a clean cheek path on optics.

Integrated sling mount and practical use

Included is a rear single-point QD swivel mount positioned for ideal sling geometry. That placement supports accuracy-aiding shots downrange by stabilizing the platform when shooting from unconventional positions or when using a sling for retention and support. For users who employ slings operationally or for hunting and range work, this is a practical advantage.

Price for the MAXIM DEFENSE PDX 505-SPS is listed at $2,183.99, reflecting the premium construction and the integrated SCW Pistol System paired with Maxim’s proven reliability upgrades. View product details and pricing

Handling, installation, and platform fit

The PDX 505-SPS is engineered to be modular with AR pistols that accept SCW components. Installation is straightforward for armorers and experienced owners; the streamlined rear reduces catch points and improves transitions during drills. Operators will notice quicker shoulder indexing and less movement when drawing from a compact carry position.
