Just to get an accurate representation of what is being said, basically, the same 127gr +P+ Ranger T that I use for carry in my G19 is "acceptable" ammunition in a G26, it just probably isn't the most optimal ammo to use? I'm not worried about losing a little bit of velocity because the barrel is so small.

I understand that 147gr. would keep it's velocity better, and understand the mechanics of dwell time and velocity. I'm just wondering if there are any other drawbacks to using this ammunition in a sub-compact other than increased muzzle flip and lower velocity retention than on a compact or full-size.
