This ETM Heavy Duty/+P Full-Size .45 ACP 8 round magazine is the perfect solution for anyone looking to use higher power factor self defense and +P ammunition. The impact resistant steel base pad, combined with an sleek black fluoropolymer finish, ensures enhanced durability and lasting performance.

The ETM with MAX spring has changed the 1911 magazine forever. Our testing has shown these to be the most reliable 8 round, .45 ACP 1911 magazines in the world. The heat-treated MAX flatwire construction never gets stressed or over-compressed like a conventional spring and is guaranteed tonever require replacement even after high round counts or daily, extreme duty use.

The heavy duty spring easily compensates for the extra slide velocity caused by heavy .45 ACP loadings and resists reliability-robbing fatigue over time. Superior Wilson Combat hardened stainless steel tube geometry in concert with our time-tested, no-tilt convex nylon follower will improve feeding with almost any bullet profile. Eliminates last round lock back and ensures last round ejection is smooth and consistent after thousands of rounds. The aluminum steel base pad easily withstands the rigors of hard, operational or training use.

MAGAZINE TUBE:  The ETM has the strongest magazine tube yet developed, virtually eliminating feed lip cracking, tube spread and cracking, and general fatigue, – some of the most common manufacturing and/or age-related defects in other magazines. The engineers working on the ETM have a combined 110+ years of firearms experience – the ETM is a showcase of their knowledge. They refined the radius for each bend in the tube to take advantage of the strength in the stainless steel they selected – and then devised a manufacturing process to provide the tight tolerances required to make those exact radius bends. The observation slots, moved to the rear of the tube, are located exactly where they need to be to maintain the structural integrity of the tube for years and years of use. After extensive testing we selected a grade and thickness of stainless steel optimized to provide superior stiffness without brittleness. No matter how many times you empty this magazine through your pistol, you can be assured the engineering expertise, design, material selection, manufacturing, and the quality control behind the ETM promises a lifetime of smooth and reliable operation.

ETM tubes are manufactured with a proprietary, custom designed welding process followed by a proprietary multi-step tumbling and finishing process. The internal and external finish, critical to smooth follower operation and insertion into the weapon, are the result of selecting the proper media and media-sequence in the tumbling and finishing process. We expended a lot of engineering time and expertise in developing the finishing process; when you get your hands on an ETM you’ll be able to see and feel for yourself, we think you will agree it was time well spent. The improvements made to the ETM’s follower and base pad have not previously been seen in a pistol magazine. This design combines advanced manufacturing technology with absolutely precise dimension control, assuring positive slide-lock after the last round has been fired. The innovative follower design with its extended skirt ensures stability in operation and minimizes creep from the tube when the magazine is empty. Super tough nylon was selected as the optimum material for the new ETM follower due to its proven durability and slick surface finish. This slick finish and the super smooth internal finish of the magazine tube result in the smoothest follower operation possible. Experienced shooters will notice this ultra-smooth performance when loading and firing.

MAGAZINE SPRING:  The ETM with MAX spring has changed the 1911 magazine forever. Our testing has shown these to be the most reliable 8 round, .45 ACP 1911 magazines in the world. The heat-treated MAX flatwire construction never gets stressed or over-compressed like a conventional spring and is guaranteed tonever require replacement even after high round counts or daily, extreme duty use. Maximum strength-up to 25% stronger than standard 1911 mag springs for superior reliability with defensive and +P loads and more positive slide lockback.

BASE PAD:  The ETM’s almost indestructible base pad provides a sure grip when pulling a magazine from a pistol or a tight pouch especially in a combat or competitive situation when seconds count in reloading. If you have ever been in the rain, trying to get a traditional magazine from a wet, tight pouch, you’ll really appreciate this feature and it might save your life.
