For the kind of money they cost and the quality of the overall gun, why in the hell would they not use steel MSH's? I need or care about hand checkering. Machine checkering is just fine with me. But the plastic MSH thing is pretty ridiculous IMO. Had to vent. I'm in the process of changing out all my Kimber MSH's with EB 25lpi versions and changing out all ambi safties to single sides.
