I'm not a Glock owner anymore but have had a few. I've never had or personally known anyone that had one bust out like that. My personally opinion about them is you hear more about Glocks doing it mainly because there are more people running around with them. Still tons of cops have them and they sell well in the private sector too. If one was to try and figure out how many rounds total from all the Glocks out there then average it out I'm sure that the numbers wont look much if any worse than any other gun maker.
If this is bugging you then maybe you need to look at another weapon. Lack of confidence in a weapon is a huge liability. You have to be able it trust your life to your weapon or it's about as useful as a paperweight. You'll have ot do the 70's cop show thing and just throw it at them.
