Left grip is different between the two. Besides the cutout for the de-cocker movement, the screw holes are in different location. Someone sells a grip set with an extra left grip so they work with either style of pistol.And notice that these are listed for the De-Cocker model!
not all grips are created equal as in the case of the PT9 & 92 there is the de-cocker and the non De-Coker models and I am pretty sure they will not interchange.
