Thanks your replies gents, good to see they are still enjoyed, will post pics of mine when I get time to do. They are battle worn, but shoot very accurately, my grandson loves to shoot them, they have also won me a few medals in the old military pistol competitions we have down here in Australia.
One of them shoots the 148g wadcutter superbly but does not like the 158g SWC of any persuassion, the other is the complete opposite will only shoot 158g SWC to a fault with 4.5g of Unique. They will be his one day.
I also find the magna grip aids accuracy but must use the original grips in competition. They are pretty hard to come by these days in Australia, the grips and the guns used to be advertised regularly years ago but not any longer.
Although the double action is a long pull, its superbly smooth, the triggers are heavy but that does not seem to hinder accuracy. I think they got it right!!
