Hey Larry, the G44 slide is the same size as the 19 and the original shoe plate of the MGW pusher works great. I have two 44s but my adjustable sights on them were too tall for the MGW. I have done a couple of other 44 sights on mine though. The lower rails are still steel.
I take extra precautions when pushing steel sights onto the polymer slide-upper, by making certain that the slide is perfectly perpendicular to to the MGW, and then pushing a little, then backing off the MGW screw tension to relieve any potential edge gouging - then pushing a bit more, backing off tension, etc. Something like you may do when using a tight tap. MGW should know that there is no problem with the original size plate.
I happen to have TruGlo TFXPro adjustable on one, Hi-Viz FO adjustable on the other
I do have the more slim plate for the Slimline Glocks, and that works well for those.
