if you can't protect you and yours with 5, you can't do it no matter how many rounds you have
This type of comment is often casually made here and there. It is simply wishful thinking! Usually offered by someone with a low capacity gun.
Let's start by realizing that handguns are VERY POOR STOPPERS. Yes, it's entirely possible that 5 shots might be enough to stop an attack on you or your family.
But then again, think about how quickly those five shots will be fired and how unlikely any one or two of them are in causing a doped up, pumped up, muscle bound, cold-hearted, cold-blooded killer to drop in his tracks instantly.
Do you think all five will all strike the target perfectly? Do you realize that two or three or four of them, or ALL of them, may miss the target as you scramble to protect yourself in the heat of a sudden, violent confrontation? And even if you do get two solid hits, do you think the perp is going to instantly fall to the ground and cease the attack?
Are you sure you won't find yourself in a situation where there may be two or three (or even more) people threatening you? There are so many possible ways for this to happen. And all you have are 5 shots before your gun turns into a stone? Reload? Yeah right... not very likely in the heat of close encounter defense. I'll take a five-shot gun over none at all, but not if I have a choice.
Do you quote the old statistic (probably coined thirty years ago) that *most* defense encounters are over within three or four shots? If you bank your strategy on that statistic, why don't you bank your strategy on the statistic that you are not likely to ever need to use a gun to defend yourself - therefore, don't even both to be armed.
I submit that these days it makes a LOT of sense to carry a gun with as high a capacity as you can comfortably handle in a caliber as potent as you can manage. Perps don't instantly fall down when they are hit by bullets. You may have two or three or four jacked-up heartless jerks to deal with.
There is a good possibility that it may take FIVE SOLID HITS very well placed in very rapid order to bring an attacker to the ground quickly. After your five are spent, assuming you were fortunate enough to have made all five of those rounds count perfectly, what do you do about the other guy or two who are hell bent on taking you out? Throw the gun at them?
Certainly 5 shots is better than none. But greater capacity is ALWAYS much better. Plan for the worst and hope for the best. Don't plan for the best and find yourself having to deal with the worst.
Every choice you make in life involves a compromise. Whatever you gain, you give something up. Can't get around that. I love .45 and have a lot of guns in that caliber. My favorite guns are 1911's. I also like .40 and 9mm.
BUT, for me, after considerable study and thought, I have chosen the Glock 23 which is a compact, very concealable, stone reliable CCW which carries 14 rounds of .40.
This is NOT my "favorite" handgun, but it is my smartest choice in a CCW because of the reliability, capacity, and potency. I like the gun a lot, I like the capacity a lot, I like the reliability and durability a lot, I can shoot it very well, and the caliber is a reasonably good choice for a handgun. Your mileage may vary.
Just some thoughts.
