Hi all, I bought a new G21 about 4 months ago, have only put around 500 rounds through it because of work. I have been reading some articles about the glock 21 and KB ( kabom ) problems. This is the first I have heard of this, I have owned a G22 and a G23 in the past and never had a problem. I always thought of glocks as being the ideal gun. Im just wondering if anyone else has had this happen to them? I let my wife shoot my guns alot and dont want something to happen. Thanks all!
