Once you add the Pierce Grip You realize the size of the pistol is essentially that of a Glock 19...
From the front of the grips, you are correct; but if you carry with a forward cant, that extra inch on the 19 MIGHT be enough to make it harder to conceal. (refer to my 1911 bobtail comment) I own a 17, 26, and 19 - there is quite a difference - for ME - in concealability, shootability and weight.
