History
Developed as a compact .45 ACP variant for subcompact carry pistols. Uses a shortened case while maintaining the same rim diameter as .45 ACP, enabling use in modified .45 ACP pistols with a barrel and magazine change. Designed for concealed carry applications where full-size .45 ACP is impractical.
