I'm purely a range guy too. I liked the target grips as I naturally grabbed them at first, until I read some threads here where I learned I was sort of holding it wrong. At first, I gripped the gun rather low, as someone here said "like one of those automatic guys." Apparently I need to grip the revolver up high, so the webbing between my thumb and trigger finger are as high on the backstrap as it can go. When I did this at my next range session, I discovered I dealt better with the recoil and was marginally more accurate. So I was sold.
I originally bought the thin service grips admittedly because they were cheaper than replacement target stocks, but when they're on the gun I also grab it naturally in the high position. I've actually not shot the gun yet with these stocks, so I guess that's the real test.
Today I was thinking about getting some Jordon Troopers and trying those out.
