Bob: "Thinking about it the GP is more L-frame size vs. the N-frame of the 610..." At 37 ounces I do not consider the GP100 "L-frame size". For comparison of 4" barrels, a S&W Mountain Gun in 44 mag weighs 36 oz. and a Taurus Tracker 41 mag weighs 24 oz. I do not grasp the concept of a 37 oz. 40 Short and Week. But whatever floats your boat. Just for comparison purposes I get 1265 fps with a 250 grain WNGC bullet from the Taurus. I do get the concept of a semi auto 10 mm but no way is any 10 mm an equal to a 41 mag.
