To answer the queston directly: neither one, and here's why...
I had a Redhawk 5.5" and gave it to my buddy in a trade for a couple of reasons.
One is that I'll be getting a Desert Eagle .44 as part of the trade!
Two is that I prefer Hogue grips on my firearms and they don't cover the backstrap, so the web of my hand gets POUNDED, causing my Bus Driver's arthritically challenged hands a LOT of PAIN! No kidding.
I have arthritis in both hands that just wasn't taking what the Redhawk dishes out. My hands are smaller than average, so switching to a Pachmayr Decelerator grip wasn't a good option...it made the trigger reach too long.
Therefore, I've committed myself to getting a Ruger SuperRedhawk in .44 until my buddy comes through with the DE44.
The SuperRedhawk has the totally covered grip peg and will provide much needed cushion for my hands.
I don't have any SmiffenWessins - YET.
I have a Hogue grip for a K/L Frame that will need a home someday.
Come to think of it, I have a Hogue grip for a 1911, too...hmmmmm.
Better get that DE44 Hogue grip NOW!
