I abstain until I know the purpose. I have a 9 mm Glock (G26) and a 92FS. They are both good pistols, but they are good for different things.
Between Glock and Beretta the biggest factor is choosing the trigger system you like. Both have their advantages. Without meaning to be difficult, I am afraid I don't fully understand the oft-voiced objection to DA/SA. I don't have dazzling handgun skills, but I didn't find it hard to learn at all, and I continue to switch back and forth between trigger systems with no problem. I have to wonder if the same folks refuse to cock a DA revolver for the sake of only having one type of trigger.
