Browning is without a doubt the #1 most important/influential. His impact went beyond handguns as well. My case for putting Glock with Browning is that Browning influenced handguns were the dominant design for a 100 years, but they have been largely replaced over the last 30 years by Glock influenced designs. If you look at handguns today, Glock is the most impactful person.
