Nice pick up. I have both a 19 and 23 for off duty work and they are comfortable to carry and easy to maintain.
You may run into some people at the range "informing" you that Glocks (especially the 19 and 23 with the shorter barrel and grip) are inherently less accurate than their (insert whatever wonder gun they speak of). Don't buy into it. These guns are reliable and can be as accurate as the shooter - within limits. They do not match my more specialized 1911 but then again, they do not need to. They are purpose built and are designed to be used.
Anyway, have fun, and practice, practice, practice! :victory:
