How Many Cartridge's And How Much Does Power Mater

if you go with statistical data, most lethal confrontations are at under 10 yards and under 6 shots are fired,
the truth is each situation is different and unpredictable,
you won,t know how far, or how many shots are needed until the threats over,
,you'll want to have the ability to keep shooting until the threat is no longer present.
guys point to the military swapping to the 9mm,
this was never intended to be a soldiers primary weapon.
keep in mind only hits to the attacker's vitals really mater.
even a 22lr can be lethal,
but Id point out that most law enforcement suggests a 9mm-38 spc, 40 cal,
is about the minimum required, and personally Id want a minimum of 6 shots ,
in a revolver or 10 cartridges in a semi auto and Id carry a spare mag or a couple speed reloader's for any revolver
and experiences of thousands of handgun shootings suggest recoil levels ,
with the 41 mag and larger handguns is generally not conductive too rapid accurate shooting.
but its been my experience that with practice a 41-44 mag, revolver,loaded,
with proper ammo is easy to manage,
while theres plenty of evidence that shows its where you hit an adversary ,
more that what pistol or revolver was used,handguns punch holes, rifles and shotguns,
have been proven to be more effective, but are not easy to carry or conceal.
I think you choice in cartridge and handgun selected does mater a good deal!
Ive used both a revolver and semi auto handgun to hunt deer and hogs,for decades,
and theres a very noticeable difference in the reaction too a well placed hit in the right place,
and its obvious that a 9mm or 45 acp has no where near the same instantaneous effect.
a 41-44 mag revolver has a pronounced and obviously more devastating reaction,
compared to very similar hits with a 9mm-40 or 45 acp.
a 445 DWSM or 454 cassul are very effective.
now I'm certainly not suggesting you need a magnum, for personal defense,
and certainly a well placed hit from a 38 or 9mm is lethal
but if your life may depend on getting rapid incapacitation of your antagonist,
you may benefit from carrying the more powerful caliber choices available,
IF you can handle the handgun fast and effectively and are willing to carry it daily,
and
IF your willing to practice with your personal choice in weaponry consistently.
every choice you make is a compromise think through your options carefully
it does you little good to know your attacker will eventually bleed out and die 15 to 45 minutes,
after hes killed you, with that knife over $30 in your wallet,
because you selected an easy to conceal pistol,
that was hard to operate or hit with, that did not rapidly,
incapacitate your attacker.

the FBI has determined that a pistol or rifle projectile that will consistently exceed at least 12" of penetration, but not exceed about 18" of penetration in ballistic gel to produce the desired results on a human target without having a huge potential for producing external damage well beyond the intended target once it passed through that target.

personally I've come to see the 357 mag, 10mm and 41 mag as about the ideal compromise in power potential range, accuracy, penetration and accuracy in controllable size and concealable handguns , provided the correct ammos used in a quality handgun of course, in the ideal world you want the ability to rapidly and repeatedly and accurately place your shots out to a reasonable distance, that means excessive recoil is to be avoided, of course your skill and practice level effects your choice and ability to do that.
these would be effective but may not be especially easy to conceal

the 10mm pistols (glock and 1006 & S&W)Ive used for decades both shoot best ,
with the 175- 200 grain bullet molds alloy used is 95% ww and 5% pure tin.
I would strongly suggest you DON,T try for absolute max velocity/pressure loads as generally accuracy suffers a great deal,
and cases get damaged if unsupported
in the feed ramp area of the barrel.
while a load that's only 25-50-75 fps lower may produce very good consistent accuracy, and goo case life.
from a practical stand point I feel the 10mm is a bit better/ ( marginally more power) than the 357 mag,
and its designed for semi-auto pistol use.

well lubed cast bullets produce far lower bore wear than jacketed projectiles.
bullets in the 175-200 grain range provide a consistent bearing surface for accuracy with cast designs, lighter weight cast bullets, may not at peak velocity.
blue dot and herc 2400 has been the powder,s of choice,
as with all handguns precise shot placement is critical to getting good results,
hard cast bullets tend to penetrate far better/further than hollow point jacketed bullets
if you miss the games vitals thats not going to be hugely advantageous, but given the fact
,youll seldom have game standing at the precise ideal range or angle,
so extra potential penetration is generally helpful

When I start carrying once my license arrives. I plan on carrying my 40 cal, I have 2 extended mags of 15 each and 2 standard of 13. I actually am more accurate with the longer mags due to me having bigger hands the extended mags give me more area to grip!
