Carmel,
My apologies, I should've mentioned this before. Not all M2 pouches are made the same, I at first had one that didn't fit but another member had the L5 that fit perfectly in an M2 pouch.
I called SOE gear mentioned to them it's being used for an L5 not an M2, they made me a 'custom' one for me. Basically they moved the upper clip 1 inch lower on the top latch, so it meets the bottom clip a bit lower. This therefore gave more slack to accomodate the L5's larger bezel. They were very helpful don't hesitate to call them and request the same adjustment.
Good luck
Good luck...
