How long has +P and +P+ ammo been around for?????
 
Just wondering how long these types of ammo have been around for i heard from someone. About the early 70's i am not sure but i am curious by the way how is +P and +P+ ammo created like what is it stronger powder or what?????

Also i have a Astra Constable .380 semiauto pistol i believe it is from the 1960's or 1970's i believe. I have only used FMJ/Roundpoint ammo standard pressure rounds in it so far. Do you think it can handle +P or +P+ rounds without blowing up????? I would carry +P or +P+ ammo in it for concealed carry since it is a small caliber as you know it is a .380 aka 9mm short.

Also i haven't tried this yet but would +P or +P+ ammo work with my Rock Island Armory M1911A1FS GI .45acp without blowing up? anyone have trouble with this gun feeding hollow points?

Is +P+ a lot more powerful then +P ammo and why?

There is technically no such thing as +P .380 ammo. Some companies advertise ammo as being +P just as a marketing ploy or to warn you it exceeds SAAMI specs. The .380 is generally fired in an unlocked breech, blowback pistol. These types of hanguns generally require a narrow range of pressures to safely operate.

I would avoid any .380 ammo labeled as +P.

The only calibers that can truly be called +P are 9mm, .38 Special, .38 Super and .45 ACP (maybe .257 Roberts).

I guess you could say that +P ammunition dates back to Elmer Keith. He loaded up very hot .44 special cartridges that were basically 44. magnum loads in the .44 special case.

i reserve the right to be wrong again but the first commercial load was probabily the old 38/44sw which paved the road for the 357mag (thanks Elmer), followed by the Supervel in the 50's maybe.

You're probably right on that. I know that Elmer was the brains behind the magnum cartridges, but I've not read too much on him so I just know the story behind the .44 magnum. I watched the history of the Magnums on the History Channel via Youtube, and it was a great source of information.
