I prefer concealed carrying, most of the time. For my Glock 19 Gen 5 I use my Galco Triton 3 Kydex holster. It*s the best holster I*ve used so far. Is there one that*s better? Better is subjective, obviously.
Let me know your opinions. To me the thin, yet sturdy and doesn*t move around construction are the most important factors of a concealment holster.
Thanks and stay safe.
