1. Glocks have too light a trigger.
Answer: Ridiculous!
2. Glocks do not have a manual safety.
Answer: That's true; and therein lies Glock's greatest mechanical fault. The necessary conscious decision to, 'go hot' has been removed from the mental decision making process.
3. Glocks do not have a magazine disconnect.
Answer: So what? In the past 40 years I've only heard of two police officers who relied upon a magazine disconnect in order to save themselves from being shot after their pistols had been wrenched away from them. With what the average gang member knows about firearms today, this old ploy is meaningless.
A magazine disconnect is not a necessity. The vast majority of the time Cooper's Four Rules of Gun Safety should suffice to cover any and all other situations. (Your safety is between your ears - Right!)
4. Glocks suffer more “kabooms” than other handguns.
Answer: Well, there's no doubt that Glocks have done exactly this. (Two of mine did.) We, all, need to recognize and understand that Glock, GmbH, has used the ingenuous and gung-ho American gun buying public to field test all of their new, 'plastic wonder pistols' in order to finally achieve that infamous, 'Glock Perfection' these pistols are now justifiably well known for.
5. Glock’s customer service, when good is great, but when bad, is abysmal.
Answer: Unless you're looking for a free pen or a key chain Glock factory service absolutely stinks - Period. I honestly believe, in fact I am convinced, that Glock factory service is the worst of its kind in the world.
In all the years I've been shooting and with all of the guns that I've owned, Glock Tech Support is the only group who has repeatedly lied to me. These guys have turned the expressions: 'Are you sure it's not the ammunition?' and, 'Are you limpwristing it?' into industry and gun forum cliches.
