This is such a sore topic around the nation and its crazy. People need to realize that gun laws are for people who follow laws. You think drug dealers go and purchase their firearms from the mom and pop sporting good shop? Do you think they register their firearm with police? Do you think they care if the gun has pre or post ban parts? Big NO. Sorry but in the past two months i have taken a stolen .357 revolver, with serial numbers filed off, from a 15 year old kid, and a 44 Colt revolver from a drug dealer on a traffic stop.
Let me also hit on the 9mm bit, i carry a Glockl 21, .45 caliber semi-auto with a 13 round mag, and off duty i carry a concealed Glock 30, .45 caliber semi-auto with a 10 round magazine. That is what most refer to as stopping power, because a person can get struck in the hand, and the .45 caliber hollow-point round with drop them in a heartbeat.
And lastly, defensive shooting means shooting as accurately and quickly as possible before you get hit. If this were a perfect world, we would only need 3 bullets, double tap to the chest and one in the head to neutralize the aggreser. Sorry if I offended anyone, but i think gun laws are ok, but i think they need to get harsher punishments for felons who possess a firearm.
