.45 ACP +p

The CorBon 185gr JHP load gets 1100 FPS out of a 5-inch M1911A1 pistol, and the muzzle flash is big. The bullet would still be accelerating in an 18-inch barrel. You may even get 1800 or more FPS out of the long barrel.

For HD the Just Right Carbine .45 ACP Is loaded with hollowpoint ammo. For range 230 grain FMJ. I was told to not use +P because of the blow back operation. Just Right has redesigned newer guns to work better with +P .

I never thought that blow-back operated firearms could be so finicky.

The bore diameter is .452"? There are a lot of .45 ACP factory loads and bullets at .451.

Get a shot gun. Best home defense weapon made for normal folks.
Actually, in MO, I can. I occasionally do carry a Kel-Tec RFB in 7.62x51. With a CCW, ALL legal weapons are permitted to be carried concealed.

Before you ask why, let me tell you, I HAVE seen firsthand some of the evils of men, and don't intend to become one of their victims.

My understanding was they are. I have done several 'melt' jobs on my carry guns, and researched the subject extensively before putting file to metal.

To operate correctly, the weight of the slide and the return spring(s) are 'tuned' by the designer to work with a particular class of bullet weight and chamber pressure. If either of these are altered by the user, say, by using +P , +P+ or larger or smaller handloads, the gun may now be out of 'tune' and not operate properly.

Yep, blow back. It still shoots everything and anything I put through it thus far. For now, I use PDX-1 230gr JHP. I've put 100 rounds of those and another 600+ rounds of various .45 ACP rounds.

Since you want to use the same round for both handgun and long gun, I think you are on the right track. Any of the premium 230gr rounds will do.

If it expands at range, great. If it doesn't you will get a through and through.

Up close and personal, the 230gr may over expand, but I have done a good bit of testing and even when the bullet over expands it still does a nice job of penetrating and a 451 hole is not that bad.

I guess that there is a lot to blowback-operated pistols and carbines
