I know the Gen 3 is THE Glock. Still known for the insane reliability, the ability to handle the famous Glock Stress/Torture tests etc and something like 20 years in the making. How does the Gen 5 stack up to the 3 in terms of reliability and durability? I have never owned a Glock, but Im looking to pick up a 19 sometime in the near future (if I could find one) as a winter EDC. Thanks all!
