I don't know if they still make them but they used to make a bolt on shroud for the hammer. If hammerless is needed then a 442 or 642. I would NOT reccomend the superlight magnums that are out there, with magnum rounds some have been known to have the bullet jump crimp and lock up the revolver. In addition the recoil is a lot heavier which sucks for range time and qualification time.
Here's a toast to our wives and to the women we loved. <pause> May they never meet.
The M1 Garand rifle is the best battle implement ever devised by man.
