With respect to curves, either get used to a new one or fight the trends via custom, pro-stock, two-pieces, etc. It just got to annoying for me to find PM9s so I transitioned to an 88.
As far as why the push to toe curves, the old man in me will shake my fist on the porch and drone on about kids these days just wanting to toe drag and then go bar down in tight to the net. The pragmatist in me will just adjust to a new curve and then be sure to duck if I'm behind the net and a young gun is winding up in the slot.
