.45 ACP Dual Purpose Loading: A Look at Loads for Carbine and Pistol Use

The .45 ACP is a low pressure cartridge. Muzzle flash is limited and standard loads do not stress the firearm. Accuracy is often good to excellent. A modest charge of fast burning powder is all that is needed. Cartridge cases will last for many loadings.

The .45 ACP doesn’t gain much velocity in a 16 inch barrel. Most of the cartridge’s powder energy burns in a 5 inch 1911 barrel. The carbine may exhibit a gain of 50 fps. The .45 ACP doesn’t become a speed demon in a carbine. The advantage of the carbine is all about easy handling and accuracy. A person who has a difficult time with the pistol will excel with a long gun.

The recreational value is high. With practice a .45 ACP carbine is a great home defense and ranch gun for moderate range use.

I've always liked the "cowboy concept" of having both a handgun and a carbine/rifle which utilize the same ammo. For "all around" use like plinking, pest control, home defense, etc. it's a nice setup. I've never really thought too much about combining a semi-auto pistol with a more "modern" carbine utilizing the same semi-auto pistol cartridge, but evidently it is fairly popular.
 
I have always gravitated to 45 in fact a SA 1911 in 45 was the first semi auto handgun I ever got in 1992 I found a used but nice mil spec with Hogue grips. Then got a Sig 220 in 1994 when I joined a PD

Don’t quite get all the hate on the 45 other them some that like to go cyclic or have a John Wick Fantasy always bring up capacity

I really wish Ruger would make the PC in 45 and have Magwells for 1911 (like the Marlin Camp Carbine) Glock or M&P magazines

Me too, although my first ever was a 7 1/2" Blackhawk which had the 45 LC cylinder AND a 45 ACP cylinder. I shot a lot of 45 LC rounds topped off by cast boolits through that thing.

Me three here! Wouldn't that be wicked cool?
 
Not trying to be picky, but did you mean the LC carbine? The PC models all seem to be 9mm on Ruger's site.
May be. It is my brother's gun. I am load developing a sub that is accurate and quiet. I haven't even had it out of the case. Also, pcc stands for pistol caliber carbine. That is what I meant.

Gotcha. I had to go try to find what you were referring to on Ruger's site. I've been aware of the 9mm "PC" model for a while. I guess I must've slept through the release of the 45 ACP/10mm/5.7x28 LC model. Now I've got a hankerin' ... My curiosity is gonna cost me some $$. Methinks I "need" both the 10mm version and the 45 ACP version. Thanks a lot! :cry: :(:);)

You might find the article at this link helpful. I found an almost identical writeup by the same author on the same guns / same loading data elsewhere, but somehow I can't find the breadcrumb trail back to it.
