Three 44's, I really like what you wrote. Now, I'm full well a SA kind of guy, but what you wrote pertains to all big wheel guns. You definitely nailed one point, and I failed to bring it up in my post, but it has helped my shooting (of everything) a great deal. To go with my SBH, I have a matching 3 screw Single Six, that I run 100's of rounds of 22 ammo through very often.
One other thing that I do is to dry fire my SBH a bunch. Not only does it help continue to smooth the trigger, it helps improve your accuracy almost as much as firing rounds through it.
