The G19 was always my favorite Glock...
My first Glocks were Gen 5 G45/19/26, then I got a used Gen 4 G23 and the finger humps kicked my a** until I put on a Hogue Handall.I love the G19 but those damn finger grooves killed me. They made it uncomfortable to shoot after awhile. When the Gen5 came out I was head over heels and haven’t looked back. IMHO it’s perfection for its intended purpose
