I have the Nill version of those grips , I almost went for the KSD for the price, but having already owned Nill match grips for my revolver went for the Nill. also how the Nill matched to the back of the frame as well as meet the front of the frame grip that little bit closer and makes a huge difference in comfort and grip.
Can I ask how the swell is if any? I might pick up a set for my 1977 short rail.
