Here is the Glock Safe Action system, broken down Barney-style: Pull trigger, gun go BOOM! No pull trigger, gun no go BOOM. Doesn't get any more basic than that.
Which are all fine and good but the trigger safety is overrated. Most people who shoot themselves with glocks are those who absentmindedly holster their gun while their finger is in the triggerguard.
No offence to you Briman, but if someone is stupid enough to holster their weapon with their finger in the trigger well, or simply violate the Third Safety Rule (Keep your finger straight and off the trigger until you intend to fire), then their newfound, and well deserved, limp will serve as a stark reminder of the virtues of proper gun handling techniques. No amount of safetys in the world will save an idiot from himself. Manufacturers could make a gun more complicated than a 1040 Long Form and some retard would still figure out how to shoot himself, or somebody else with it, but it still wouldn't be the gun's fault.
I personally like the Glock's a great deal. A custom match-grade 1911 they are not, nor are they meant to be. They are rugged, dependable and accurate enough to serve their purpose as a defensive weapon well. They are a no-frills combat pistol that is meant to be carried and used under the most extreme circumstances. If I had to go into a firefight with nothing but a pistol, then I'd take a Glock over a "nickle-plated-sissy-pistol" any day.
Recently I've also had the opportunity to size up the new Springfield XD's, and I will say that I am impressed. They point very well in my hand (I hear that from a lot of people), seen to be reliable (time will tell), and the price is right. I would definately buy one to try out should the opportunity to buy another handgun arise in the near future.
