Why This Beats The Competition
Having run 500+ rounds through this Gen 6 at our Spring TX test range, three things stand out:
- The MOS system actually holds zero better than aftermarket plates I’ve tested on previous gens
- New grip texture bites just right – no need for Talon grips like I’d add to Gen 5s
- Forward slide serrations are deeper than Gen 5, giving positive traction when clearing malfunctions

Who Should Buy This
Buy it if: You need a duty-ready pistol that’ll run 10,000+ rounds without hiccups, want optics capability without aftermarket milling, or prefer Glock’s consistent trigger pull for defensive use.
Skip it if: You’re chasing a competition-ready trigger out of the box (see our 1911/2011 options) or need a micro-compact for concealed carry (consider the Glock 43X).
