Promag Standard SR Magazine: Heat-Treated Steel for Reliable Defense

When reliability matters in a defensive loadout, spare magazines deserve as much attention as the firearm itself. A robust replacement magazine reduces the risk of feeding issues and keeps your Ruger SR mission-capable during training, range days, or home defense scenarios.

Design and construction

The PROMAG STANDARD uses heat-treated steel for the magazine body, which increases wear resistance and structural integrity under heavy use. The injection molded mag follower helps ensure smooth feeding and reduces the chance of tilting or binding in the feed lips. The mag spring is formed from chrome silicone wire, chosen for spring resilience and corrosion resistance—a critical factor for magazines carried in varied conditions. Made in the USA, this magazine reflects practical construction choices that prioritize reliability.

Brand and model notes

This offering comes from Promag, a brand known for affordable aftermarket magazines, and is listed under model designation Various to reflect compatibility across Ruger SR variants. At a street price of $20.99, it’s an economical spare that doesn’t sacrifice essential durability.

Compatibility and field use

The PROMAG STANDARD is explicitly compatible with the Ruger SR platform. For defensive-minded shooters, keeping at least one dedicated spare magazine like this on-hand minimizes downtime during drills and provides redundancy in a worst-case scenario. Its steel body stands up well to repeated loading, drops, and holster or pouch carry. For range users, this magazine is a cost-effective way to practice reloads and malfunction drills without wearing on factory magazines.
