  • Patented Extended Skirt, ANti-Tilt all Metal Follower Ensures Lock Back and Increases Feed Reliability in all .40 S&W 1911 Pistols
  • Maximum Tensile Strength Heavy-Duty Spring for Long Service Life, Enhanced Feeding and Positive Slide Stop Operation
  • Removable .350" Plastic Base Pad for Easy Maintenance and Versatility with Different Base Pad Options

  • Metal Spacer Ensures proper Feeding with Factory .40 S&W Ammo


NOTE: For use with .357 SIG 1911's the magazine's inner rear spacer must be flush or slightly taller than the bottom of the U-shaped tube cut at the top of the tube.  This will ensure that the bottleneck .357 rounds do not nose-down feed from rim drag on the spacer.  To adjust the spacer, remove your baseplate and spring/follower assembly and tap the bottom of the inner spacer with a punch towards the u-cutout at the top of the magazine until it is flush. See additional images for spacer/U-shaped tube cut relationship.

Wilson Combat® has been supplying serious shooters and professionals with the worlds' most reliable and durable .45 auto magazines for the past 30 years. They are used by the worlds' most Elite U.S. Army SPEC OPS unit, FBI SWAT, Thunder Ranch and professionals worldwide. NO other .45 magazine on the market can compare for proven inherent reliability, durability and the ability to remain fully loaded for long periods of time without damage. Our magazine springs are specially fabricated from the highest tensile strength heavy duty spring wire for long service life enhanced feeding and positive slide stop operations. Our magazine bodies are manufactured from .025" (the thickest in the industry) aircraft grade certified 17-7 PH stainless steel and heat treated for maximum durability and service life. Our 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 are tight inside the tube as long as your pistol and ammo are close to proper specifications.

"Back in 1980, Bill Wilson asked me to test some of his new Wilson-Rogers .45 magazines. He explained that he felt they had solved the problem of cracked feed lips and that their new magazines fed much more reliably than any others on the market. Well, it's 30 years later now and I'm still using some of those original 6 prototype magazines that Bill sent me… Through the years they have proven without a doubt to be the most reliable and durable 1911 magazines on the market. I have personally used specimens from various production runs through the years and have yet to see any quality variation or have one let me down in any way. They are my first and only choice as well as the choice of the elite special forces units I train. I trust my life to a Wilson Combat® pistol and 8-round Wilson magazines; so can you…"

Mag-nificient! 1/10/2014
Ordered these to use in my Para Pro Comp 40, these mags function flawlessly. These are quality mags with the added bonus of 9 rounds. Added a Wilson bullet proof magwell and I now have smooth and fast reloads. Pros: Fit, finish, extra round. Cons: None!

Awesome Mags! 3/14/2013
Throw your Upla or however you spell it in the trash, these things load themselves. Lighter than factory, even w/extra capacity. Dont worry, theyre pretty to look @ too. Highly recomended.
