The model 83, large frame, Freedom Arms revolvers...are all 5 shot guns...so it'll meet your needs perfectly ....and they make guns in .44 mag and 6" barrels ...or whatever you want basically.
I have a large frame, 4 3/4" octagonal barrel they made for me in .357 mag and its a great gun - premier grade.
Here's mine...
