So, I am in the midst of recovering from a near-fatal TBI that broke my helmet into four pieces. I have a 34-year memory loss, which has wiped out a bit of my cartridge knowledge. Anyway, I am trying to decide which Glock would be better for personal defense here in fully-clothed NH. I already have a G17, but I am considering a G22. Seeing how the S&W .40 is a somewhat new cartridge, I need to know what the overall track record has been for the G22/23 and the .40 S&W cartridge. Is it significantly better than the G17/19 and the 9x19? I have to keep in mind that a third of the time up here in NH folks wear a few more layers of clothing than the folks in FL do. Thank you!
