I had the good fortune of working as a part-time public range RO - it intro-ed me to some interesting firearms. I shot two of the 3.75" Bird's Head Grip Vaquero in .45 Colt; both exhibiting a tendency to 'lose' their base pin and have somewhat ineffectual ejectors. I elected to get a standard length base pin & ejector - and bought a closeout 4.625" version. It is a keeper - in fact, my BH and SS Bisley BH in .45 are long gone now. Ultimately, I bought a .32 H&RM, .357M, and converted a new 4.6" SBH to a BHG - all having black Micarta grips. Neat common grips - rolls with recoil - especially that .44!
I did try a Thunderer and another shortie with a 'true' BHG - I prefer the rounder Ruger interpretation. The 'real' BHG would seem to be held more rigidly - and probably not rotate under recoil. Still, I kinda like that one in .45 Colt & 3.5" barrel...
My 6" h-l 629 replaced my 6.5" 24's as a modern easily cleaned .44 Special, although it sports X-frame Hogues for recoil, just in case I want some poop. If that 6" 29 is a RB, you might consider the grips I tried - only available from S&W Accessories now - the .500/.460 Magnum X-frame Hogues (They fit the RB K,L, & N-frames, too.) - $35. When I carry the 6"-er, I find myself popping rifle plates at 100 yd, the 4" or so revolvers generally finding the 12-15yd plates.
Odd how we hurt ourselves! My CTS problems arose after retiring from teaching math and math-utilizing courses - lots of chalk on the blackboards. My years of model-building, woodcarving, and wood turning, my last vocation, made my retired enjoyment of my .454 SRH short-lived. Now, .44 Specials, mild .45 Colts, .45 ACP/AR's, etc, are my maximum loads - I really seem to enjoy my .32 H&RM/S&WL and .38's. The absolute worst recoil to me has been a DE in .50AE - not the straight recoil, but the twisting moment when the rotating bolt stops and transfers it's rotational inertia to twisting my wrists - a big ouch. Uncanningly, the vertical rotation of the Ruger BHG in my hand, accentuated with .44M's in that SBH/BHG, is far more comfortable for ME to shoot. It is very individualistic, of course.
Oh yeah, I found my favorite .45 Colt revolver - after going through .454 SRH, .45 RH, and an assortment of SA .45's - the S&W 625 Mountain Gun - I have two of them - that 4" tapered tube makes for a great 'pointer'.
