We don't have a .44 special, but my wife TOOK OVER my 625 .45!!
so I can't compare to the .44 special, but I know my 625 5" I bought for revolver class got taken over by my wife...
she HATES the recoil generated (to her) by autos. We tried all 9mms (S&W, Glock, Taurus, Browning) and a few .380s (Browning and a few cheapies) and hated them. She shot my 1911 once with my 170 pf hardball ammo. Never would touch it...
now..i get a 625 from a friend, put some Miculek grips for me to shoot revolver class...it is now her pistol and will stay with her during the divorce (not sure if there is one on layayay or not
)
she can shoot factory WWB hardball, my 170 pf loads, or Federal Hydrashocks and she doesnt' feel a thing. It's the 5" barrel, so maybe it has enough heft out front but she loves it. She also shoots our 686, M64 3", and Model 10 4" and she will swear that the 625 recoils/moves/flips less and is quicker for her to index. it's also the only one she is comfortable shooting DA.
she's not a big girl either, 5'6"/120ish...but we don't have a .44 to compare. I think the .45, if you want a large bore, is the ticket. ammo is easy to find. we bought a $7.00 screwdriver-like tool to flip empties off the moonclips, and I bought enough we can load up 240 rounds to head to the range, and then it honestly doesn't take long to snap the empties off..haven't tried the plastic ones
my wife's opinion..she's happy with the 625...sorry had to chime in :O)
