Today was the first time since I bought my 25-2 in 1981 that I heard that "…25's have a cylinder throat problem." I thought that was confined to Rugers (but not mine.)
Luckily, my guns, both S&W and Ruger, seem to have been spared that fault, since both are one-hole shooters. Against all expectations regarding the long cylinder jump, mismatched throat and barrel diameters, etc, .45 ACP revolvers seem to shoot pretty darn well.
