The Glock 19 was the opposite for me. I had, and loved a Glock 23, so the 19 seemed like a perfect fit. So much so that I bought two of them. But, after a couple of years, I just could not warm up to the 19 and ended up selling them both. I do keep a 9mm barrel for my G23, so I can test the waters from time to time to see if I've changed towards the 19.
