Alright,
I went to the range with my older son today and we took a few revolvers along. The SP101, GP100, S&W 65, and the Service Six.
It was an uneventful session, the Service Six performed flawlessly. I had the service grips on and it was kind of making accuracy a little bit harder - particularly with .357 Magnums! But the accuracy was good enough. I might change the hammer spring to a lighter weight eventually.
The SP101 is a gem; with the Hogues it is surprisingly accurate. The GP100 performed as well as always but the star of the day was my old S&W 65, the trigger is just unbelievably smooth and since we do most of our revolver shooting in double action, the difference at 15 yards on paper plates is visible!
The service Six has passed it's test with flying colours and will be used as a car gun by my son, most likely.
