Are your Glock mags dropping freely and performing consistently? If not, you should give our MBX steel magazines a try. We developed a seamless, one-piece steel body Glock style magazine. We improved the reduction angles and added a second stage near the top to maintain a fast and consistent “nose up presentation”. We engineered the body of the tube to correctly stack, align and feed 9mm tapered cases. The tubes have been heat treated and tempered for consistent performance and durability. The base retention lips are infinitely stronger than the plastic and will not fail when you need extreme durability.
