I don't just figure it. I know it to be the case from personal experience. The 19 has a greater amount of flat surface area in contact with the body, thus spreading the pressure against the skin over a larger area (lightening said pressure per square inch), and thereby reducing felt pressure against the body. Additionally, a longer slide helps stabilize the weapon positionally such that the forward edge (by the muzzle) of the slide is placed at a more favorable angle for comfort, i.e., less bowing outward at the grip end, so less bowing inward at the muzzle end. The weight difference is so slight as to be inconsequential compared to those other factors.

PS For the reasons stated above, the 17 is even more comfortable IWB than the 19.
