I keep reading---and this is a carry/self-defense forum---bout a number of things that don't involve theirownselves with these choices.
#1 is price:
Now, I know the first one to post will say that the object to a gun fight is to have a gun.
I disagree on many levels. The gun---wheather a roller or semi must function.
#2 Then there is esthetics:
The police have not space in reports for how pretty the gun is that killed someone.
#3 Material:
Refer back to #2
If it does not function all of the police reports will be about the gun the other guy used to shoot you.
My choices are based on very conservative values.
If I own it, it WILL function. I am going to spend good money to assure this. It will be accurate--see the money thing.
Now---eventhough thare aint no way to report it---I am going to be proud to carry it. Read--pretty. If I loose it, I will loose one I am proud for another to put his hands on.
Steel is a first choice---well, second, third and only choice.
I keep a scandium under the matress----that is steel--but I don't like it---it is just one that I don't mind being under a matress.
Blessings
Almost any gun you buy,from the 100 dollar Zamak gun to a 3500 dollar custom 1911 will function. Also,ANY gun you buy will malfunction. Thats why I think that price is the single most important criteria. In other words,no matter how much you have to spend,there is something "better" out there if only you are willing to spend more money. Put another way,no matter how good a gun is,its not going to do you any good sitting in the display case at your local gun store. If you dont have the money to buy it,it does not matter. How much is my life worth to me? Its worth as much as I can afford to spend and that will change as time goes by.
In short consider all the guns out there,now eliminate any that you cant afford. It does not really matter how good they are,becuase you cant afford them. If there's more than 1 gun left on the list,go to the next criteria. If there is only one,then its better than nothing.
Second is suitability for what you need it to do. A full sized 1911 isn't much good if your 100lb,5' tall and need something that you can conceal on your body under light clothing. Theres going to be overlap here between the other categories. If you want something to protect you against bears,anything that is not large enough to do the job is out.
The third most important thing is reliability. If it does not go bang,its not much good. Its not #1 or #2 though becuase all guns go bang,at least sometimes but an empty holster never does and for instance,there are very reliable 22s,but your better off buying bear spray than something that small if that's what you need to defend yourself against. So take all those guns you can afford,that are appropriate for the task you want it for,and weed out all but those you consider reliable enough to be of use in a fight. Your going to end up setting the bar here arbitrarily. Revolvers ARE more reliable than semi autos,but many of us consider a good semi auto reliable enough. If the list contains more than one entry, keep going. If there's just one thing on the list,you found your gun.
Fourth is accuracy. This is not the inherent accuracy of the gun,but how well YOU shoot it. This could be hard to tell,unless you can rent one. If you cant all you can do is hold it in your hand and make a guess as to whether you will like it based on how it feels and how accurate it is for other people.
Fifth I think is stopping power. Not those tables you find on the internet saying a 44 magnum is better than a 357,but stopping power of the whole weapon. In other words a single shot 44 magnum would be a poor choice of a self defense weapon even if you could hit accurately with it (and it should be VERY reliable) You really want more than 1 shot though becuase your first shot might miss or might not stop him. The 45acp is much less powerful,but a 8 round 1911 is much more likely to stop an attacker all things considered than a contender in 44 magnum. So stopping power here means not only is it big enough,but does it have a high enough ammo capacity. In other words,does it have enough of a powerful enough cartridge to get the job done.
All the other things I think really go under one of these becuase these are really what guns are all about,throwing a chunk of lead at a target reliably and with enough energy to do its intended task. If after these five,there are still several on the list,go back to price reliability,suitability,accuracy and stopping power and choose one with a mix you feel comfortable with.
