I'm not sure exactly how to ask this question but let's assume you own no handguns at all and you want to buy one for self-defense. How do you decide which attribute is most important? As an example when I'm looking at a handgun these qualities (in no particular order) have to be there. Reliability Concealablity Capacity Weight Aftermarket support Commonly available There are other things than those that I look for that I could list but after those six things everything else becomes pretty irrelevant. There are also other things that I look for (commonality) that would be deal breakers for me but in my example I don't have any other guns so it's irrelevant. Reliability is important. I won't carry a gun I don't trust but assuming I'm buying from one of the major manufacturers and I didn't get that 1 in 100,000 lemon reliability is a given. Capacity is important. I said in the other thread that I won't carry less than 10 but the truth is if the choice is between carrying less than 10 and carrying nothing I'll carry less than 10. Weight is a deal breaker for me. If the choice is between a heavy gun and no gun I'll carry a heavy gun but if the choice is between to somewhere guns one steel one polymer I'm carrying the polymer gun. Concealablity is again important but realistically I have yet to meet a handgun (unless you get ridiculous and want me to conceal a Colt's Dragoon in a speedo) that I can't effectively conceal on my person. Commonly available I'm not going to carry a CZ82 or a Tokerov or Makarov because they're "cool" hipster guns. If Walmart doesn't (before they went Bloomberg) carry the ammunition for I'm not buying it. Aftermarket support is one of the big reasons I carry a Glock. I mean you could throw a rock and you're going to hit somebody that makes a holster for Glock or magazine or new barrel or an 80% lower. So if I had to list them in order it would have to be Reliability Commonly available Capacity Weight Concealablity Aftermarket support.
