I went through the guns side ny side.
Mag release is different, and the gun comes with aluminum grips which are flush in the frame.
My modified shadow grips, or the original wood groups have a space.
The frames looks identical, the mecgar mags are thinner. My official CZ mags are NOT interchangeable.
Not sure why it was changed, but i can confirm some batch of TS's that come with magwell, aluminum grips and mecgar mags, ARE different.
