About the Single Action Ruger vs. the Double Action S&W and Colt in .41 Mag, some shooters prefer the single action grip design of the Ruger over the DA desing of the Colt and S&W.  This is true of heavy loads.  The SA design tends to rock back and pivot in the hand helping tame the recoil.  The DA's don't seem to do this.  While it might be not as important in the .41 Mag, it does make a difference to the .44 Mag shooters.  Many of them like the Ruger .44 Mag because of this bit of trivia.  Don't worry about missing one pistol.  There are other .41 Mags looking for good homes.  If you preferences run to that caliber, one of them will eventually pop-up on your radar screen and you'll just have to have it.  (I know about these things.  Trust me on this.)
