Forty Rod is right. I packed an 1878 41 caliber DA in my chap pocket for years, until I wore it out about the year 2000. Cimarron came out with their "Thunderer" about (in?) 2001 and I ordered a grip frame and stuck it on a Uberti 45 SA Sheriffs Model that was factory stocked with a "birdshead" to help control the recoil produced by heavy charges of smokeless.
Each to their own. Ten plus years later, I think the stock plow handle grips of the SA (Ruger, Colt or Repro) are really hard to beat. The grips for the 1878 Colt though really fit that pistol.
