Actually, the Glock is kind of a double action, the striker pin is only partially cocked when the slide is racked, squezing the trigger pulls the striker pin all the way then it releases it (kind of like a sling shot).
So in fact it can be compared to a DA pistol, where the trigger pull operates the hammer then releases it which then stricks the firing pin.
An SA pistol only does the releasing of the hammer part of the firing sequence.
If your worried about light trigger pulls, the best way is to install NY (New York) trigger spring and disconnector, my NY2 gives me about an 8lb trigger pull which is comparable to a revolver. For a CCW pistol application this is added safety.
SA's need safeties because of the small amount of trigger pull required to fire.
