Joe, I have shot a half dozen Glocks and feel similar to you. Clunky, ugly, reliable, weird grip feel near the bottom. I shot one that the lower part of the grip was "shrunken" and it felt okay.
I personally don't see a need to buy one as I have no interest for a striker fire pistol. But, my buddy did just get the new HK vp9 and I shot it. The grip is amazing and the gun is only 625.00. I won't be buying one as I am still not going to buy a striker fire gun . But maybe you want to look into that as an option?
