I would very much recommend the Gen 4 Glock 21 or Glock 30. I can't specifically talk about the Gen 4 30... but I can the gen 4 21... and it has become my favorite Glock of all time. It's absolutely perfect for me. Carries well, recoils light, good trigger, not too heavy. I'm definitely interested in the Gen 4 G30 as well.. but I'll probably get the Gen 4 G20 first because I want the dedicated 10mm as my hiking/camping/woods gun.
