Ah, so you did.
I read this to be:
Model 25, 9-inch, 45 colt cartridge...
My bad. Not being current on revolvers, esecially S&W, it got by me.
Now I really feel for you. Remember: Sight Picture, Trigger Control, is everything. Carry lots of ammo. Never stop to pick anything up off the ground. Fire and forget; never check shot placement in paper (trust your instincts, Luke).
