Here is a link to CDNN/TargetsportsInc...they are a reputable outfit I've dealt with them and have had only good things to say. They don't list their prices on the GLOCK as they are below wholesale, they sell new and used/trade ins. They have a toll free # to call and inquire. As far as GLOCK goes my favorites are the 9x19 chambered pistols, I have a 17, 19 and a 26. The 9 is inexpensive to shoot and with the proper load very lethal and very controllable. I've had the GLOCK in .357SIG, .40S&W as well as .45ACP....I just like the 9mm probably cause I can shoot it well:target:
