Can anyone tell me the purpose of the 2 holes in the front part of the frame of the M model?
Are you talking about the 2 rectangular slots on each side of the frame under the muzzle?
If so, that's a proprietary rail design for attaching accessories. As for what accessories fit... Good luck with that
Like cold said - it's for a rail adapter. Odds are you will not be able to located anyone with one for sale, but it may be worthwhile to contact IGB (via MDW Guns) if you are really interested.
