Experience the Proven Tripp Research CobraMag Legacy

For decades, Tripp Research has led the firearms industry by designing magazines trusted by competitive shooters, law enforcement professionals, and serious firearm owners. Most notably, Tripp Research invented the original 2011 CobraMag, creating a magazine platform renowned for flawless feeding, exceptional durability, and unmatched reliability.

Building on that proven heritage, the CobraMag DS9 combines advanced engineering with precision manufacturing. As a result, every magazine delivers the smooth, dependable performance that discerning shooters expect. Furthermore, every design feature serves a purpose, ensuring reliable function under the toughest conditions.

Precision Engineering Delivers Consistent Performance

The CobraMag DS9 begins with a precision-machined, through-hardened 410 stainless steel magazine tube. Consequently, the magazine maintains exceptional structural strength while resisting wear through years of heavy use.

Next, each tube receives a high-luster polished finish. Not only does this finish improve corrosion resistance, but it also reduces friction, allowing cartridges to move smoothly throughout the feeding cycle.

Additionally, every magazine features Cobra Tuned feed lips that skilled technicians precision polish and individually inspect by hand. Therefore, every round feeds consistently from the first shot to the twentieth.

To further enhance reliability, CobraMag equips every magazine with a high-tensile steel spring and an anti-tilt, self-lubricating polymer follower. Together, these premium components maintain proper cartridge alignment while promoting smooth, consistent feeding throughout the entire magazine.
