H&K, Glock, SIG, and the rest are all reliable, accurate (enough), and durable.
When I was looking to buy a new handgun, my primary interest was in reliability. I knew that all the guns I on my list had a reputation for reliability. Therefore, I used such factors as ergonomics and features as the means to personally distinguish different handguns. I already own a glock, and they fit me pretty well; however, I must cock my wrist forward in order to align the sights. I just do not like the feel and controls of SIGs, though I could feel the quality. H&K's, though I bit thick, fit me very, very well. I also happen to be a proponent of cocked and locked carry. All-in-all, H&K was the gun that I kept fondling.
Truth be told, I cannot wait for the HK45. I don't care about it because of the hype; it just happens to be exactly what I want from Heckler and Koch.
