Wilson Combat has supplied shooters and professionals with the world's most reliable and durable .45 ACP magazines for over 30 years. These magazines are trusted by elite U.S. Army Special Operations units, FBI SWAT teams, Thunder Ranch instructors, and firearms professionals worldwide. No other .45 magazine on the market matches their proven reliability, durability, or ability to remain fully loaded for extended periods without damage. Magazine springs are fabricated from high-tensile-strength heavy-duty wire to ensure long service life, enhanced feeding, and consistent slide-stop operation. The magazine bodies are constructed from .025-inch aircraft-grade certified 17-7 PH stainless steel-the thickest in the industry-and are heat-treated for maximum durability and longevity. Tight dimensional tolerances ensure every Wilson magazine drops free from the pistol and maintains proper round alignment, provided the firearm and ammunition meet standard specifications.
