Well, aren't we Mr. lucky...a four inch 441 in .44 special. Yes, I'm jealous as heck.
BTW, it will be tough finding a holster for it, I managed to find a 4 inch Safari Land holster that is made for a Colt, its a number 25 stamped on it.
But the holster strap was not quite long enough to reach the secure snap...had to use alcohol rubbed into it to stretch it, along with some clear leather oil.
Now it does the job of holding my model 441 with 3 inch barrel, and also double duty as a .45 Colt Tracker with 4 inch barrel.
Found this holster at a pawn shop for $15.00 out the door.
