• Easy tool-less slide pin tube attachment
• 9mm OAL up to 1.165 can be used in MBX extensions
• Round view slot with capacity numbers allows you to load round count you need with confidence
• Easy maintenance with one screw baseplate removal
• Custom designed Wolff extreme duty spring 28 coil for Mega
• For 9mm Factory Glock and ETS Magazines
• Plus 26 Rounds on Glock 31
• Will Not work on MBX Glock Steel Magazines
FYI:
OAL in testing using factory magazines. We recommend if reloading to start between 1.145-1.155. This stacks well in the tube but if you wish to push out longer than do so cautiously as different brands of tubes. Internal sizes can vary, too long will cash slow bullet rising.
Crimp is very important to magazine feeding. Be sure to keep at factory specs. It’s easy to measure we use Winchester white box that comes in .374-.376. Incorrect large crimp will case slow bullet rise and stiff loading.

The new gold standard for PCC
After a month of random ammo, shooters and match styles I can confidently say the MBX "Mega" mag extensions are the new heat for the PCC division. I have had 100% reliability with absolutely zero modification to the magazine. The index marks line up accurately and the design is incredibly well thought out. Buy them before everyone else does!!!
