I had to switch to shooting revolver one-handed last year, thanks to age and injuries. So, I now shoot with left hand instead of right, as well as left eye instead of right. Learned a few basics all over again. One is that shooting revolvers one-handed places a real premium on EVERYTHING being right. Two of the very important basics are the old standards of excellent trigger pulls and fit of grips to my hand. When I finished working on my Rugers, they are much easier to shoot accurately, as well as being much more comfortable with full loads. Will list and describe the basics that helped me most.
1) Lots of dry fire practice, followed by live fire at paper targets. I did this both with arm supported and without support. That really taught me how much control I had to have to hit 4-6 inch targets every time at 20-50 yards.
2) Did lots of work on my revolvers to get the trigger and hammer pulls to where I could control the let-off easily and cock the hammer with minimum disturbance of aim. This ment working on the sears, NOT the springs, of the triggers -- this is NOT FOR THE INEXPERIENCED!! Ended up with nice crisp, totally repeatable and reliable trigger pulls slightly lighter than the weight of the revolvers. Hammer pulls are only slightly lighter than factory and were arrived at by slowly shortening the hammer springs and doing lots of practice cocking after each shortening. Since these are trail guns too, the hammer springs cannot be so light as to cause missfires in cold, nasty weather -- I also use only CCI350 primers.
3) Very careful shaping of the grips to precisely fit my left hand. This consisted of a loooonnnnnggggg series of sanding off about a mm at a time at those places where my hand pressed hard on the grips, followed by lots of dry and live firing. After a while it became obvious that what was working was that I had a firmer grip on the guns, WITHOUT needing to have a death grip on it (really important for those that have physical problems that reduce hand strength). That is, my hand and fingers had greater and greater areas of firm contact with the grip. Steadily, ease of hitting smaller targets increased, whereas felt recoil decreased as did amount of disruption by recoil of gripping of gun. The final (at least for now) result is a set of grips that still look just like they did originally, at least to casual inspection, but that fitt my left hand so much better as to be a revelation.
I have handled only one factory revolver that fitts my left hand as well as these Rugers now do.
Hope this is useful to someone.
