HAVING A CARBINE CHAMBERED FOR THE SAME CARTRIDGE,
THAT YOUR PISTOL IS CHAMBERED TO ACCEPT,
AND IN SOME CASES USE THE SAME MAGAZINES IS,
IN SOME CASES A GOOD IDEA LOGISTICALLY AS,
YOU ONLY NEED TO STOCK ONE TYPE OF AMMO.
and interchangeable magazines
EVERY CHOICE YOU MAKE IS A TRADE-OFF IN SOME AREAS
(THINK THROUGH YOUR CHOICES):D:rolleyes:
I can't really see a need for any pistol cartridge in a carbine,
when you have at least potentially several dozen much more powerful and longer range options.

but a pistol cartridge , choice does make a great deal of sense in a suppressed carbine config
now of course that choice of a pistol cartridge does tend to limit both your options and in most cases long range effective use ,
but in a personal defensive weapon use at ranges exceeding 150 yards or so is very rarely needed.
And if you think about it, you're unlikely to burn out a 10mm carbine barrels rifling in a lifetime of shooting.
where as a 223 /556 might only last 4000-5000 shots before accuracy is less than ideal, at longer ranges, in a carbine.
(keep in mind barrels are fairly cheap, usually in the $120-240 dollar range and any gunsmith can change one in under an hour on an AR15 platform)
now personally I don,t think the advantage of having a single ammo caliber,
used to feed both a pistol and carbine is a valid concern or any major advantage
,in the bigger picture, as the loss of power and range, especially in a carbine.
if limited to using the pistol ammo only,
is too great a sacrifice in the carbine's versatility in my opinion.
but there are some exceptions, and a 10mm carbine will lead a long happy life using cast bullets, something a 223 will not do.
but the lower power pistol ammo does have the "ADVANTAGE" of being a bit safer to use in a home defensive environment
, as it will tend to penetrate fewer internal walls ,beyond the intended target,
and its a bit less likely to take out unintended personnel, or family members,
if you miss the intended target, home invaders, or carjackers etc.
in that intended usage, and recoil and muzzle flash is far more limited.
Id say its use has a noticeable advantage, in limited areas, and a 10mm carbine would be ideal,
and it also has the punch to use for hunting deer and hogs, and it will work with a suppressor,
much better than a caliber like 223 rem, as a 200 grain bullet in a 10mm cartridge can be loaded sub-sonic,
yet still retain an effective punch against the intended targeted home invaders, or carjackers etc.
and at limited ranges, and ESPECIALLY IF USED with a suppressor,
not be all that damaging on your hearing or have the excessive muzzle flash in a dark room that some calibers might have.
personally I think a 10mm AR15 clone, carbine that used Glock 10mm mags is one good option

looking over the graph results a 12"-13 barrel carbine/pistol chambered in 10mm would seem to be a good compromise,
in both ease of handling vs potential performance & muzzle energy.
(for a combo, personal defensive weapon that could be used for hunting)
a pistol or carbine like that, properly loaded with good ammo,

would both provide the accuracy and power required for personal defense/ home defense,
and hunting medium game like hogs & deer and make 100 yard shot placement fairly easy,
I'd point out that the 200 grain bullets have much better penetration than the 135 grain.

having tried several pistol caliber carbines over the decades, I consider them to be more a toy, than something you might stake your life on!
while punching holes in a few coke cans in very rapid succession at 50-75 yards can be a lot of fun, and the ability to kill small and medium game is certainly available if your very careful about where you place shots, and are aware of the cartridge limitations,
if I were to carry a carbine, I think the AR15 chambered in 6.8 SPC with a 12"-18" barrel and collapsible stock,
makes a great deal more sense as a personal defensive weapon choice, and carrying a 10mm glock or a S&M 1006,
as a back-up certainly does no harm, its simply the case that if your going to carry a 5-7 lb carbine having ,
it chambered in a cartridge with much greater range and penetration than any pistol caliber carbine has makes more sense.
the one area where a 10mm carbine makes a lot of sense is if you use a SUPRESSOR, as a 200 grain bullet pushed too just under sub sonic velocity with a suppressor makes a lot of sense as it allows a good deal of power in a suppressed carbine
