Wilson Combat has been supplying serious shooters and professionals with the world’s most reliable and durable .45 ACP magazines for over 30 years. Introducing the Wilson Combat Elite Tactical Magazine: No other magazine available can compare for proven and inherent reliability, durability, and the ability to remain fully loaded for long periods of time without the spring taking a set or losing tension. WC magazine springs are specially fabricated from the highest tensile strength heavy duty spring wire for long service life, enhanced feeding, and positive slide stop operation. WC magazine bodies are manufactured from .027” (the thickest in the industry) aircraft grade certified stainless steel and heat treated for maximum durability and service life. Dimensional tolerances are held so close that you will never encounter a Wilson magazine that doesn’t drop free from your pistol or that your rounds aren’t tight inside the tube as long as your pistol and ammo are close to proper specifications.
