You seem to be advocating a violation of the first rule of firearm safety. Every carton of ammunition manufactured by a SAAMI member incorporates some form of the warning, "Use this ammunition ONLY in firearms marked and chambered for use of this cartridge." Read the headstamp, stupid! If your firearm is marked "45 ACP" then that is the ammo you should use. Warning: Do not shoot 45 Auto factory ammunition in the following firearms:
Taurus PT1911
Kahr P45
FNP45T
EAA Witness 45
Check those headstamps, stupid!
It is not possible to debate someone who doesn't know the difference between a cartridge headstamp and the caliber designation on a firearm.
It's the headstamp,stupid!
Good bye.
