I'm a big guy and find a 3" more uncomfortable to carry than a 2". That extra inch seems to make a big difference when sitting, interfering with seat belts, etc. I settled on a 640 Pro because it is easy to conceal, handles .357 (though I rarely shoot them) and has outstanding sights. The sites are the best I have found on a fixed sight gun and makes the gun very accurate. Barrel is only 2.125" but gets the job done.
