After doing some research and shooting, I've decided on getting a .45 for home defense. I really like the HK USP .45 and the glock 30. I've shot both, like both, but can't afford both (at least not yet) . I wanted to conduct an opinion poll (about which one to choose) based on the following criteria: 1) quality of constuction 2) reliability 3) service life / durability. Any owner stories would be appreciated as well.
