My newly bought SS Hartford Rossi '92 would not take 10 rounds so I whined about it on the SASS Wire and I was told to take off the magazine cap and there was a white plastic spacer/plug in the muzzle end of the mag. They said to throw it away and reinstall the magazine spring (without needing to cut it). The gun immediately held 10 and maybe even 11 rounds of 357. Another option is to shoot 38spl in it since they are shorter than 357mag ammo. This was a gun bought in about 2000. The plug was about 1.5-2 inches long.
The older '92 I bought used in 1993 did not have the spacer and always has held ten rounds.
With over 15 perCUSSIN' revolvers, I've been called the Imelda Marcos of cap & ball.
