Default HD carbine: 45acp vs. .223/5.56

I've got a list of firearms that I need in my collection before I just go into "buy cuz it's fun" mode. Three of my needs are a home defense carbine (short and shoulder-fired), I need a second gun that fires .45acp (everyone knows that two is better than one), and I need a second AR-15 (parts interchange is important). Eventually, I'd like to have 3 separate guns to fill all 3 roles, but for now, I am thinking a single AR-15 in 45acp might do the trick.

Olympic Arms makes a smokin' 45acp upper with proprietary mags that fit a standard lower. Then I'd build a pretty standard lower from parts. It would cost about $1200 with a good trigger and mid-range red-dot scope.

What do y'all think about .45acp carbine vs. .223/5.56 for home defense (not talking 100 yards-plus, I've got a 5.56 20" AR for that).

First Ar? If so, get a .223/5.56 ammo is cheaper and mags are cheaper. If you really want a .45 AR just get the .45 upper and swap it out when you feel the need. If you can get an SBR as I don't think 16" of barrel is going to do anything for .45acp in fact it might actually slow it down as pistol powders burn fast and there isn't much of it in comparison to a rifle round.

Nope, not my first AR. I agree that 45acp ain't a first AR kind of round. Federal 230gr. +p LE rounds will not be slowed down in a 16" barrel, but probably sped up by about 150 fps from what I've read. That means almost 600 ft-lbs.

I am budget-conscious here, which is why I'm talking about filling multiple roles with one firearm.

There is a very good reason most LE SWAT teams have abandoned SMG's for entry guns; overpenetration. A good pistol hollowpoint bullet will penetrate further through residential walls than a good frangible .223/5.56 bullet. I have not seen/heard/experienced many good things about Olympic arms rifles.

My vote is for .223/5.56.

Can you define your roles and need?

I thought I did. 1) HD carbine (my 30-30 isn't quite right), 2) 2nd 45acp gun (my 1911 commander needs a buddy), 2) 2nd AR-15 (chambering not all that important)

These needs could be filled by a 5" 1911 and a 16" AR in 223, but my question is whether an AR w/ 45acp upper would fill the roles well.

Ok,

You said you want a short one...are you going to SBR one?

How big is your house/apartment? Do you have neighbors close by? Are you worried about over penetration?

Do you have a big yard? What ranges are you planning on shooting?

What I'd do:

5.56 AR- Get a 14.5-16" middy gas set-up. Aim for a sub-7lb rifle. I'm building one such rifle right now and finding the best quality/price ratio from BCM, Spikes, and JoeBobOutfitters. If you want to buy complete, Daniel Defense seems pretty tough to beat in the $1200-1400 range (not sure how much you want to spend). Good deals can also be found on a number of the higher end 1:8 twist S&W rifles.

Pistol Cal carbine- I like 9mm for such a job. Very quick follow-up shots, flatter trajectory if you should desire an extended shot, cheap to feed, high capacity, and plenty of power (9mm 16" barrel ballistics ~ 357mag pistol). You can go with an AR, Beretta CX4, Marlin Camp, Kel-Tec, even Hi-Point...whatever. Lots of options in 9mm. I went with the Kel-Tec S2K. Super light/compact/manueverable, quick target acquisition, affordable (under $400), and it takes 30+rd G18 mags.

45acp Pistol- 1911 Government. Remington R1 Enhanced is a pretty great gun for $750 IMO. SA TRP if you want to spend a bit more.

Funny...I'm finding it very easy to spend your money.

Do the AR first. There's already a ton of pull on supply, and it'll only increase in the coming weeks and months.

I'm not a fan of a pistol caliber in the AR and would recommend a 5.56 pretty much like what Sweeper22 spelled out. For a 45 why not get a 1911. An AR and 1911, hard to argue with that. If you really want a pistol caliber AR, think about the 9mm.
