Howdy
First off, Ruger does not make a Blackhawk with a 4 3/4" barrel. Although one of the standard barrel lengths for Colts is 4 3/4", Ruger barrels are 1/8" shorter at 4 5/8".
OK, School Marm mode off.
Here is my SASS gunbelt. Two 2nd Gen Colts, one with a 4 3/4" barrel, the other with a 7 1/2" barrel. These holsters have a bit of forward cant. I wear the 7 1/2" Colt on my left side with the butt forward as a cross draw holster because I discovered a long time ago it is difficult to draw a 7 1/2" barreled Colt on the strongside without getting my elbow tangled in my arm pit. Cross draw eliminates that with a long barrel.
Although I do not carry every day, my experience with the 4 3/4" Colt carried on my strong side is that I do not have a problem sitting down. The long barrelled Colt tends to bump the seat when I sit, but the 4 3/4" Colt does not bump the seat.
Of course, this is wearing the holsters on a wide (2 3/4") gunbelt. Wearing the holster on a narrower belt may cause the holster to ride differently.
If it wuz me, I would get a holster that I could wear on either side until I decided which way I liked best.
