Glocks have to go?

I was recently reading the Counter Strike Source section on Steam forums when someone suggested that Glocks are overpowered, unbalanced and are basically unfair being semi auto with the burst function. I'm not too sure about those comments but the Glock does reasonable damage, minimal recoil + the ability to shoot 3 bullets at once. Image it's a hostage map, there's 3 terrorists camped using Glocks + burst fire and you've got 1 minute left to try to get the hostages , You rush in, then get instantly spammed by 3 "Glockers". There's no chance you can get past 3 "Glockers" all using burst fire camped, waiting for you to enter though a 1 metre wide doorway.
