Virtually ALL the nice handguns have been or are being discontinued. SIG's P225, P228, the non-rail P229, the Beretta 92FS stainless, 92 Compacts, virtually all the S&W 3rd Generation 4xxx and 6xxx series autos, the HK P7 series, Browning-marked Hi-Powers, and so on. Call it the Glock phenomenon. Since Glock showed how you could make an ugly pistol that was durable yet cheap everybody else eventually had to cave in and make something similar. Nothing against the Glock, but to me it's a simple tool with no soul. I like guns I can admire and collect, as well as take out and shoot or carry to save my bacon. Nothing new out there even strikes my fancy anymore, so I tend to find gun stores extremely boring unless they have a large selection of used guns.
To be honest, I haven't bought anything new in recent years. All I have now are old designs, and that's probably how it'll stay.
