Ya ought to try my SBH in the .44 mag with that Dragon back trigger guard William, on some days I would come home from the range a bloody mess but not always.
Strange that it started today---which was the actual concern
This seems to be the question. One thing that I noted upon the first deer hunt with that SBH is that with near full power loads, that razor blade of a trigger guard never touched my knuckle! This did not dawn on me until I was doing the field dressing chores but did catch my intrest on why this happened?
My thoughts returned to the hunt. A deer will definitely catch your attention as will my little 2" steel plate that hangs next to a 3" and a 6" out at the 50 yrd line, Novelty targets, or the ones that you really like also qualify. Under these conditions, it seems that one completely forgets about the firearm in hand with all concentration being on the breathing, sight picture, and pressuring up that trigger. The shot goes off and all is well.
Back at the range though, some of the targets are just not that interesting. A hit is going to go without question and perhaps concentration shifts to the Revolver in hand rather than addressing the target and the sight picture?...perhaps one will hold onto the gun too tightly and the shooter will grip it even tighter along with trying to crack it like a whip which can be observed if the hammer falls on an empty cylinder. The involuntary flinch can bring about all sorts of problems and perhaps knuckle busting is one of them?
This is not going to be a cure all because different frame sizes along with different sized hands are going to demand some modification at times. Seems like if one is relaxed and addressing the target it can go a long way though.
