In the best LE/SD loading's, 9/357/40 are all good rounds.
The G27 can run all three calibers.
And you can use the next size up barrels (4.02") if you want
the extra ballistics.
That versatility is the real strength of the G27 IMHO.
It allows us to individually find the best caliber/round we
are most proficient with.
Not paper comparisons of FPS or muzzle energy.
Putting bullets on target in a high risk, high stress, situation is the key.
