The 9x23mm Winchester was designed by John Ricco and introduced in 1996, after much time was spent in courts on
patent infringements by Winchester.
The 9x23mm Winchester is designed with a very thick web (case base) so as to handle 48,000 P.S.I. (pounds per
square inch), so, for this reason,
never use a 9x23mm Winchester in a 9mm Largo pistol, as the 9mm Largo pistols are
not built to handle that amount of pressure.
Some shooters consider the 9x23mm Winchester cartridge to be the best caliber available for the 1911 pistol frame,
but the cartridge is used very little today.
