Will the 365x Macro Comp take the 15 round magazines?

Will not, unless someone makes a base for it (the 15-rounder). The 2 bottom sleeves that come with it are no good for the X Macro.

Here is an adapter base plate to use your 15 round mag in a macro.

Thanks for the info. Looking at an X Macro and noticed that the 17 round magazines have spotty availability and just wondered.

I am cheap. I got some used 12 round base plates and adapted them. Here is a video on how it is done. click here. Works great!!

Unless your state prohibits mags that hold more than 15 rounds, what is the purpose of going less?

Found some 15 rounds cheap. And some who list 17's dont really have them.
