Key Features – Wilson Combat ETM 500BC Magazine
Built on the Elite Tactical ETM Platform
The Wilson Combat Elite Tactical Magazine (ETM) was designed from the ground up using over three decades of 1911 experience—not just a reworked 7-round body stretched to hold eight. The 500BC ETM takes advantage of that engineering, offering: Wilson Combat+2Shooters Connection Store+2
A stronger stainless steel tube with carefully engineered bend radiuses and thick walls to virtually eliminate cracked feed lips and tube spreading over time.
Relocated observation slots at the rear of the tube to preserve structural integrity while still letting you check round count. Wilson Combat+1
A proprietary welding, tumbling, and finishing process that produces an extremely smooth interior for friction-free follower movement and easy insertion into the magwell. Wilson Combat+1
All of this is aimed at one goal: maximum reliability in real-world conditions, whether that’s a dusty range bay, damp carry environment, or high-round-count training course.
Lo-Profile Steel Floor Plate – Slim, Strong, Concealable
One of the standout features of the 500BC is its low-profile thin steel floor plate, designed to keep the magazine compact while still giving you the durability of a metal base. Georgia Guns & Ammo+4Wilson Combat+4eBay+4
Benefits of the lo-profile steel floor plate:
Slim footprint for better concealment and minimal printing in carry rigs.
Strong steel construction that holds up to hard drops during reloads and training.
Removable design so you can easily disassemble the magazine for cleaning and spring inspection. Grady's Outdoors+3Wilson Combat+3Gun Deals+3
If you carry a 1911 daily or run it hard in classes, a robust, low-snag base pad like this is a big advantage.
Stainless Steel Tube with Premium Black / Blued Finish
The ETM 500BC uses an aircraft-grade stainless steel tube coated in a black fluoropolymer / blued-style finish. This combination gives you: Shooting Surplus+3Wilson Combat+3Civil Arms Store+3
Excellent corrosion resistance in humidity, sweat, and wet weather.
A slick exterior for smooth insertion and withdrawal from magwells and pouches.
A classic, subdued black look that pairs perfectly with blued, black nitride, or parkerized 1911s.
Because it’s stainless under the finish, the tube resists rust and remains structurally sound even after years of use and carry.
Fiber-Filled Nylon Follower – Smooth, Stable Feeding
At the heart of a reliable magazine is a reliable follower. The ETM follower in the 500BC is made from fiber-infused nylon, chosen for its combination of toughness and self-lubricating properties. Wilson Combat+2Gun Deals+2
Follower advantages:
Extended skirt design that keeps the follower stable in the tube and helps prevent tipping.
Self-lubricating surface that glides smoothly against the tumbled stainless walls.
Enhanced positive slide lock after the last round thanks to consistent engagement with the slide stop. Wilson Combat+2Gun Deals+2
This engineered follower is a key reason ETM magazines have such a strong reputation among serious 1911 shooters.
Long-Life Stainless Spring – Ready Even After Long-Term Storage
The 500BC uses a high-quality stainless steel spring wire carefully selected for long service life and excellent memory. Wilson Combat specifically notes that ETM springs are designed to tolerate being stored loaded without suffering the rapid fatigue seen in some standard magazine springs. Wilson Combat+2Gun Deals+2
Benefits:
Consistent feeding tension even after thousands of rounds.
Less worry about leaving magazines loaded in safes, duty rigs, or carry setups.
Corrosion resistance – stainless steel springs fare better in humid or coastal environments.
If you keep defensive magazines loaded for extended periods, spring quality matters, and the ETM addresses that directly.
