Fishjager hit the nail on the head.

In the hands of a person who is competent with firearms, the Glock is one of the safest handguns on the market.

On the other hand,the best handgun safety systems in the world can't stop the untrained or incompetent from hurting themselves or others. For them the safest choice is a baseball bat.

The bottom line for a personal defense weapon, carried or homebound, is to be comfortable and proficient with the gun that you chose.
