It will get better with use i promise not that i thought it too bad out of the box.
I picked up a set of wolf springs, i use the 10lb hammer with the factory return spring.
Personally i found with the light return spring that i would have reset issues when shooting rapid double action. The only other modification i made was to radius the sides of the trigger for comfort when shooting double action.
After handling both the 686 and the GP100 i chose the ruger as i like the forward weight, no steel back strap in your palm, i prefer the dissasembly of this one and actually like the look of the ruger better if you can believe it.
I also like the feel of the 6 inch over the 4 as well. The extra weight makes for a faster more accurate follow up shot.
Plus the resale of the blued GP100 appears to be nothing so im keeping it.
