When comparing handguns, size matters. Wither fitting your hand or considering the print of concealed carry, we need to know how big pistols are to make good choices.

You can go to the manufacturer’s website and compare dimensions, but that can require math and may not allow you to visualize the irregular curves involved. The time honored method is to put two guns on top of each other and just look. This is problematic if you don’t have the guns in front of you.
