G27 with just Storm Lake 40-9mm barrel and G26 mags.
Runs flawless with no BTF or FTF.
Plus I can swap back my 40 S&W barrel and mag in seconds.
1000 Hollow Points and 1000 FMJ in 9mm.
But I only run 124/127 gr ammo and mostly +P or NATO.
Some folks have issues with low powered light 9mm (115 gr).
I would think that the long slide might take more energy to cycle reliably.
So high powered 9mm might be a must.
