.32 S&W Long , loaded to SAAMI pressures , JHP will not expand . In theory , a WC will have slightly larger wound channel , but RNL is much better for Speedloaders , or quick reloading generally .
How Low , is Low Recoil in the OP's context ?
Depending on brand & lot , real world chronograph from 3in bbl , 98gr RN .32 S&WL will give mid 600's to just over 700 fps . Mainstream .32H&R Mag 85gr JHP give +/- 900fps .
Oversimplified - .32 S&W Long = apr twice the recoil of .22lr . Mainstream .32 Mag = apr 1/4 t9 1/3 lass recoil than std velocity .38Spl in same size gun .
* To Me * , both are low recoil , but we don't know of Mrs Moparfreak's physical handicaps .

.32 Colt Long will bulge , and split about half the time , when fired in .32 S&W Long chamber. Ask me how I know .
