You can see from my post count that I'm new to this site and in truth to owning a handgun. I've done a good bit of research and some good hands on testing and know what I like in a handgun. I purchased a Glock 26 Gen 3 and have shot around 400 rounds with it. Very nice gun for me. I've got an opportunity to pick up a Glock 19 Gen 2 but not sure what the difference between the Gen 2's and the Gen 3's are. Is there anything that I would need to look out for? Thanks in advance for the information.
