After thinking about it more I am leaning toward the Gen 4 30. I was also initially all fired up about the 30s, but want to keep the soft feel I have in my 21 in the smaller package. I also like the capability of playing with 10mm or .460 Rowland for fun.
Where are you guys finding the Gen 4 30? LGS or online? Shops around here are dry of any Glocks.
