I have medium size glove hands and find the 43x grip to be just right. I have a Glock 27 but the 43x is my everyday carry. I’m one who obsesses over weight and combined with the slimmer profile, I can personally tell the size difference when compared to a Glock 27 being carried on the belt. Yes it is a tad snappier than a 19 or 17, but I really don’t find it to be significant. The only downside to the 43 and 43x for me is I tend to get slide bite more frequently than I do the larger guns.
