I can't believe that I am posting this (I am usually a fan of blued-steel-and-wood firearms ), but I shot a Glock 19 recently. It shot really well. I was thinking about buying an HK, but I've decided to add a Glock to my meager collection instead. After reading on the Interwebs (I probably shouldn't have done that), I saw that apparently Glock had some issues with the early Gen. 4s. I'm curious about whether those have been solved, or if it would be better to stick with the Gen. 3s. There's a used Gen. 3 sitting at my LGS. Any thoughts?
