I've taken two deer with my Glock 20. Both deer were shot using out-of-box Hornady 180 XTP's and both went down within 30 yards of the shot. The second deer needed a finisher after a poorly placed initial hit.

As of today, were I looking for a 10mm to hunt with, I'd buy one of the 2 Ruger revolvers currently offered. I just like those platforms better.
