I am looking to purchase my second Glock. I currently own a G30SF that I use for daily carry, but because of ammo availability, or lack of, and price I never really get the chance to shoot it. I originally had my mind set on a G21SF for a second full size pistol, but since I never get to shoot the G30 I figured the G21 would see the same fate as my G30. I guess I am curious if anyone else has gone to the 9mm from the 45acp for this same reason and your thoughts. I think the Gen4 G19 will be here around March if I read correctly so I have time. I'm just brainstorming at this point.
