The SIG MAG MPX 9MM 20RD THRIL – 9mm Caliber, OEM Origin Made a Bold First Impression
The SIG MAG MPX 9MM 20RD THRIL – 9mm Caliber, OEM Origin isn’t just another magazine; it represents a refined approach to feeding the insatiable appetite of the SIG MPX platform. These magazines, manufactured by SIG SAUER, promise to blend the reliability of metal feed lips with the weight savings and resilience of a polymer body. With a retail price hovering around $40, it enters a market already populated with options, each vying for a spot in your kit.
My journey to this magazine began with a nagging issue: inconsistent feeding with some aftermarket options in my MPX SBR. I needed a magazine I could trust implicitly, one that wouldn’t stutter when the timer started or when things got hairy. After all, malfunctions are unacceptable when employing the MPX in personal defense scenarios or even just striving for peak performance on the range.
Unboxing the SIG MAG MPX 9MM 20RD THRIL – 9mm Caliber, OEM Origin, I was immediately struck by the solid feel of the polymer. It felt more robust than other polymer magazines I’ve handled. The metal feed lips were seamlessly integrated, providing a visual promise of longevity and reliable feeding.
Compared to Lancer L5AWM magazines (another popular MPX option) and some cheaper Glock-compatible magazines I’d experimented with, the SIG SAUER magazine stood out. The Lancers, while aesthetically pleasing and reliable, carry a steeper price tag. The Glock-compatible mags, even with conversion kits, lacked the reassuring fit and finish of a dedicated MPX magazine. My initial reaction was one of cautious optimism; could this magazine finally deliver the perfect balance of price, performance, and durability?

Extended Use & Reliability
After several months and approximately 1000 rounds, the SIG MAG MPX 9MM 20RD THRIL – 9mm Caliber, OEM Origin continues to impress. There are only minor cosmetic wear marks on the polymer body. The feed lips show no signs of deformation or damage.
Maintenance is simple. A quick wipe-down with a dry cloth after each range session keeps everything running smoothly. Compared to my previous experiences with finicky aftermarket magazines, the SIG SAUER magazine has been a breath of fresh air. It consistently feeds reliably across a wide range of 9mm ammunition types.
