There never has been and will not be a cartridge with that designation.
For that matter, the designation ".45 ACP" was obsoleted prior to World War II and replaced with ".45 Auto". Some folks (most gun writers and almost all wantabe gun nuts) never seem to get the word.
Again, look at the headstamps stupid!
And don't waste your time and mine listing all the off-shore manufactures and some ill informed domestic gun manufactures that also are using obsolete terminology.
It is no more correct to use obsolete cartridge designations than it is to address a married woman by her maiden name.
All ammunition made by SAAMI members and other responsible manufactures carries the warning, "Use only in firearms with this designation stamped on the barrel or frame."
If you actually have a pistol marked ".45 ACP" use only ammunition with that headstamp.
Just because Caddric's have similar physical dimensions does not mean they are interchangeable, i.e. +P loadings versus non +P loadings.
“Caddric’s” should be “cartridges”
