As you know, one of the worst issues with shooting PCC is the inability of the plastic mags to perform consistently. MBX decided to take the problem head on and developed an extremely strong steel Glock style magazine.
Reduction angles have been improved with an added second stage near the top to maintain a fast and consistent “nose up presentation.”
The body of the tube was engineered 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.
