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, one-piece steel body Glock style magazine. They improved the reduction angles and added a second stage near the top to maintain a fast and consistent “nose up presentation”. They also engineered the body of the seamless tube to correctly stack, align and feed 9mm tapered cases. The tubes have been heat treated and tempered for consistent performance and reliability. The base retention lips are infinitely stronger than the plastic and will not fail when you need extreme durability.
MBX 3″, 5″, and 7″ extensions for the 170mm 9mm Steel Magazines increase capacity by the following:
• 3″ Extension increases 11 rounds for a total of 41
• 5″ Extension increases 17 rounds for a total of 47
• 7″ Extension increases 26 rounds for a total of 53
Please do not attempt to purchase large capacity magazine if you reside in any location where you may not legally possess them (California, Colorado, Connecticut, DC, Hawaii, Maryland, Massachusetts, New Jersey, New York, & Vermont).
