I would exude no perspiration over it. Since the OS 46 FX parts interchange with the Magnum XLS 46 I think you'd be safe in using the OS numbers to apply to the Magnum.

And don't forget - not only is the Magnum less expensive, it has a true chromed cylinder, not cheap-crap nickle plate like the "Higher priced" brand.

Bill.
