Best Choices for Self Defense Ammo
This is a discussion on Confusion about carry ammo within the Defensive Ammunition & Ballistics forums, part of the Defensive Carry Discussions category; But hey, on the off chance you get in a gun fight with someone from the Matrix and you miss with a 9mm it's cheaper ...
But hey, on the off chance you get in a gun fight with someone from the Matrix and you miss with a 9mm it's cheaper than if you miss with a .45 - that's a plus, right? Not to mention you can miss more due to higher capacity!
"Do your duty in all things. You cannot do more, you should never wish to do less".
General Robert E. Lee
OTOH, with a .45, if you hit him in the thumb, it'll rip his brains out through his shoulder blade, where his arm used to be!
The choice should be obvious!
Ammo choice is all about compromise, especially when you're talking about caliber and the amount of powder in the casing. Compromises like:
-Amount of recoil. Less is best.
-Ability to stop threat. Bigger caliber is always better than smaller caliber. Faster is almost always better.
-Size/weight of weapon. Smaller is often best for concealment, but there is a practical limit. Lighter guns are nicer to carry than smaller guns.
-Barrel size. Less is best, but then your sight radius gets worse.
-Amount of BOOM and flash created by the ammo.
If there were no compromises we'd all be carrying tiny guns with a 1inch barrel with 10 inch sight radius (magic!). It would have ergonomic grip that is small until we want to use it at which point it expands to the size of your hand. We'd be carrying 20mm rounds that go 2000fps and explode into an inferno once penetration reaches precisely 12 inches. There would be no recoil at all due to the special pixie dust powder used. Capacity would be 100 rounds, just in case.
Because there are so many compromises the result is that each individual trades those compromises against each other and reaches their own happy blend. Maybe they're OK with a lesser power round (9mm) because the recoil is less and capacity increased? Maybe they're OK with increased weight because they get a bigger more ergonomic gun that can pack a bigger caliber.
A lot of people don't know how to balance these compromises, or don't want to due to lack of knowledge, and so they just go with whatever some authority has gone with. i.e. picking a Glock .40 SW Gold Dot purely because the Police use it and therefore it must be the "best". Cops drive a lot of Crown Victorias too and I'm not sure that's the "best" car either.
Second, there are four types of personalities on this board - those that want to learn, those that want to teach, those that want to stir up mischief, and the non-gender specific Old Fart. Those that want to learn ask which caliber is better, those that want to teach chime in with advice, those that want to stir up mischief play the contrarian, and the Old Fart then chimes in with an ad hominems.
Responses 2 - 4 repeat in an acyclic manner for about two days, then the thread dies an overdue death until it is resurrected or spawns anew.
Most any caliber from the lowly .380 Acp on up will do its job if you do yours. Find a quality bullet and a caliber that you can shoot well and practice, train and get some training....that's how it done.
Myself I mainly carry .38spl/.357 mag, because I like revolvers and I reload those rounds. For most caliber choice is a personal preference and some swap calipers as often as they change their pants. After about 20 years of carrying I have settled back down to revolvers which is what I started with as an armed security guard way back in the 90's

It's been written before, and still is probably the most valuable advice. What YOU can control will be the best.
It's very hard to argue against the .44 magnum round for its ability to cause massive damage. It's hard to carry the gun that will fire it. The Ruger SR9c is a compact handgun that carries 18 rounds of 9mm. Loaded with Corbon DPX, it's an awesome weapon.
The Ruger LC9 holds 7 rounds of 9mm in a light, slim package. Same with similar Kel-Tecs and such.
Since I don't have the answers to these questions, I own firearms and holsters than solve all these problems.

What you can control is a given. Ignore the BS answer " I carry a .45, because they don't make a .46"......
A good rule of thumb is to carry whatever caliber and specific round that your local Sheriff's department carries, or something less than that standard. In my case, the local uniformed deputies carry Glock 22's, in .40, loaded with Federal Hydra Shocks. Detectives carry Glock 23's (.40) and/or Glock 32's (.357 Sig), with Winchester Rangers.
Consequently, I carry a Sig P239, typically with the .357 barrel, with Winchester Ranger ammo, but I have the .40 barrel and Federal Hydra Shocks, as well. While most folks do not, I like the .357 Sig round. I find I can get the sights back on target faster with the .357, than I can with the heavier .40's. the only drawback I have found with the .357 is when you fire in low light situations; the flash is appreciably brighter than that of the .40. Typically, when I know I am going to be out, after dark, I carry my P239/9mm, for that specific reason. The 9mm also has a laser grip, which is more useful in low light scenarios.
There are only TWO kinds of people in this world; those who describe the world as filled with two kinds of people...and those who don't.
THE VERY BEST SELF DEFENSE ROUND IS THE .50 BROWNING MACHINE GUN ROUND!
But since I can't carry or conceal a Ma'Duce, I compromise and carry a .357 Sig H & K P2000 SK. As I've said, shoot the biggest round you can put on target (Stop Button) shot after shot. Emptying the magazine or as many shots as required as fast as possible. Doesn't do any good to carry a 10mm if you can't hit the broad side of a barn. Muzzle flash and noise doesn't stop the BGs!
Again the record shows a 22LR is deadly if placed correctly, but I prefer to myself a little edge with my carry round!

A lot of the caliber war stuff is just based on peoples' egos. "What I carry is best because its what I carry"...that type of stuff runs rampant with the caliber warriors.
