Re: cable lock or trigger lock for semi-auto?
neither. in the event of an emergency when you need your gun you need it NOW!
imagine your hands shaking, your heart racing and you need the gun now,
you just heard glass breaking downstairs... you just woke up and your sweating you have to find the key or your keys and possibly make noise doing so. now that you have your key you have to get it in the lock, stop shaking get it lined up, you can hear a scene unfolding in your home footsteps voices.... where are the kids... ok get the clip... fumble it into the gun... where are the kids?
rack the slide... you are ready to go.
now imagine this,
Glass breaks, you wake up you're sweating you hear a voice and footsteps, who is it? your hands are shaking you pull open the nightstand door, put you hand down on the finger grooves, more foot steps... where are the kids? the door pops open grab the clip fumble into the gun, rack the slide you are ready.
It is the shallowest water that makes the most noise.
