As a gun owner, I can't think of one reason I would need a thirty round magazine.
Me either but its better to have it than need it and not have it.
A thirty round magazine is designed and manufactured to kill multiple people without reloading. That's it, no other reason.
No...it is designed to help save the life of the user....defending himself against attack and protecting his family...it allows them to do so without having to change a magazine more times than they might have to with fewer bullets......that is important because if you are injured in a fight, the adrenalin and injury may make it harder to switch out magazines...
Criminals can get whatever magazines they want and can rape rob and murder with illegal guns and magazines.....
Civilians who have to defend themselves and their families...may face more than one attacker and those attackers may be armed with their own guns.......so again...the 30 round magazine allows a good person to defend themselves and their families......
A well trained individual with a Glock can't do the same?
A rifle has advantages over a pistol....one, you can add a light and better opticals for shooting in dark and low light....like in a dark house.....the AR-15 is also very easy to shoot for all sized people..while a pistol is not as easy to shoot and to hit your target.....
The 3 points of contact that you have with a rifle means you can control the rifle better.....
And you can get Glocks with 30 round magazines......
And that is the point...anti gunners specifically state that they want 10 round magazines because they know that most modern hand guns can hold 15 or more rounds in their magazines....by insisting on 10 rounds, they ban those pistols......
That is the only reason they are pushing the 30 round magazine limit....
Then, when the next mass shooter uses 10 round magazines.....the anti gunners will go back for those...insisting that no one needs a military style pistol for self defense.....
The Sandy Hook shooter changed magazines several times...making a 30 round magazine unnecessary for his killings...and the Santa Barbara Shooter used California legal, 10 round magazines for his shootings........
There is no rational, logical reason to ban 30 round magazines for normal people.....
If you want to stop criminals from using them....add a 30 year sentence for using a 30 round magazine in a crime.....
