dont know the difference between M92FS and 92FS, didn't know there was an M92FS. There was an F which relative to the FS lacks a forward compensator. There are also a range of matt black/nickel/wood grips/plastic grips models in both F and FS models.
When I looked at the CP88 a few years ago I think it was all metal.
The 88 with dual barrels for 80 quid is a stonking deal in my opinion.
