The History Of Firearms
The 3 major and basic concerns for folks when choosing a firearm whether for self-defense or close protection should be:
Caliber - Accuracy - Reliability
Accuracy- Is a direct result of weapons training as well as the component you can most impact. Today's modern guns are extremely accurate straight from the producer. Accuracy is just not attained throughout the gun but through the operator.
So you have to train, train, train to be accurate. Then along with training whenever you are within a stressful situation your almost certainly will not be as accurate as you are at the range. So train and train some more.
Caliber- I am a firm believer that most individuals should consider shooting the biggest caliber and heaviest load that they may shoot accurately. Caliber has no affect if you can't shoot accurately and hit your target/threat.
I highly recommend nothing smaller then a 9mm, 9mm,.40,.45 are my favorite calibers. With these calibers you are provided stopping power. Accuracy should always be more important than caliber.
Reliability- Today's modern guns are built with good standards and also are mostly reliable. Choosing a handgun manufacturer may be difficult sometimes. Do your research and hunting select a manufacturer who is handguns will with stand up to the pressure of everyday use for training and practice.
The last thing you want is an unreliable handgun when you need it the most. So please review your handgun manufacturers and due your investigation. I have listed four very respectable gun manufacturers:
