You would be far better off finding an old Mod 28 in 357 if the cylinder is long eno
And do the mod, I had a 28 turned into a 44 special that way over 20 years ago by one of the best gun smiths in Indiana.
He drilled out the cylinders that way the timing was already correct for the gun.
Put a 4 inch Duglas barrel and added a spring loaded ball on the tang to make the action lock even tighter.
Thin put the larger trigger from Smith in it and did an action job.
The point was that at the time no one was makeing anything in 44 special and I have a thing for the round.
At the time the cost after aquiring the 28 (200$) the total mod was around 300$
And if some one says they can do as much mod as your talking about for $200 RUN AWAY.
One other thing, to mod a 28 is one thing, but to destroy a 45lc just to shoot 41's in not what I would consider a wise thing to do.
Any N frams smith can have a good trigger job done and match what you have now if you can find a good gun smith.
I would guess a NEW cylinder if you could find one Duglas barrel and all the work would gross out at lot more (Like 2 or 3 times) $200
