The grip shape of a Glock 19 and 17 are different enough that they should be be considered two different pistols when deciding which one fits best for an individual.
But everyone has always defaulted to the G19 because the G17 was simply too hard to conceal, and reasons.
Then Glock comes out with a G19 with a 17 grip and now everyone all of a sudden loves the bigger grip. All of a sudden it’s not hard to conceal anymore. Even though it’s about zero percent easier to conceal than a 17, and most guys around here carry a 19 in a 17 length holster anyway.
Maybe, just maybe, we just found out that full size men have been cramping their hands up on compact pistols for the past 20 years and they’ll shoot a little better with meat on the grip.
