My carry mag in my 26.3 is almost always a flat base 10rd. Once in a while, such as when driving long distance, it may be found with a 12 round factory mag and riding in a Miami classic with two G19 factory mags in the opposite side mag pouch for balance, but usually when I carry that gun, it’s partly because I want the short grip for concealment, so why would I put a longer magazine in it? If I am comfortable with a longer grip for whatever situation I’m carrying it for, I’ll usually carry a bigger gun.
That said, I usually carry the G26.3 and/or a 642. Lifestyle requires discreet carry.
Makes good sense. To clarify: In the gun, I run only a flat OEM (or OEM +2 to upscale) in the G25.5. or flat OEM (or Magpul 12 to up scale) in the G26 2.5 or 3. Because concealment. The reloads are Gen specific OEM 17s. (or OEM 19s or 26s based on locale).
