I have a pocket Glock in.40. HATE the trigger pull. Have heard of several cases of accidental firings, all with 9mm.
The trigger pulls on Glocks can be lightened, but then you are risking an AD.
All AD's can be blamed on the handler of the firearm unless the firearm is defective in some way.
The Glock was made to be safe, but it is no safer than the person using it.
