are hand guns dangerous ? yep ! in the same way a chain saw is , the same way a car is , the same way a bath-tub is !
Any machine or object can be dangerous if the person using it is not careful .
So which gun is the most dangerous ? the short answer - the one in the hands of a person who is not careful !
the person who does not know the manual of arms for the gun or the person who does not know the safety rules associated with guns .
Have your friend load a diverse group of guns ( after training ) lay each in a safe place and watch them for say 8 hrs. just to see if any display more unsafe behavior ! As you and I already know none will show any behavior , proving that the gun by it self poses no danger . It is only when the gun is touched by humans that the real danger becomes an issue .
We would have to concede that the handgun , auto loader in particular requires a bit more diligence than a in some cases because of the shorter bbl. . The fact that most carry a handgun because of law or convince is why more accidents happen with them , the same could be said for a certain model car , it is probably safe to say more fords crash than corvettes . but neither cause a crash with out a human involved !
Your friend needs to stop trying to pass the failures of the human race - on to tools, machines and objects !
I would venture to guess that the percent vs. number in use of accidents for handguns is no more with hand guns than others if all were reported . a guy carries his handgun every day and uses his rifle 2 weeks a year .
good luck with your friend but if he will not be responsible for his actions you got a hard battle to win !
you know the deal a tree was growing for 50 years , 25 years ago they build a road by it yesterday a guy hits it with his car and blames it on the tree , the car and the way the road was built ! wasn't his fault even if he was lighting a cig. and adjusting the radio ! AT THE SAME TIME !!!!!!!!!!!!!!!!!!!
