Not sure if this is what you're asking, but strictly speaking, the action of a firearm refers to how the trigger system works. Some firearms are single action, some are double action, some are double action only, some are variants. Glocks are called "Safe Action" which is Glocks propietary term for how their trigger works.
Glocks are *usually* black in color and have a very "boxy" appearance. They have no visible hammer or safety. Their sights are usually raised box sights. They can have barrels ranging from 3" to 5" and grips ranging from two finger grips (trigger plus two fingers) to full grips. Stock Glocks will have either no finger grooves or only one small finger grooves. Glocks are always handguns unless they have been modified by the user. Beretta makes handguns, shotguns, and rifles. Berettas can look like almost anything.
