You can get drop-in barrels from EFK Firedragon that extend out 1/2" which are ported. Those won't spray garbage all over your front sight like the one shown on the 17C where the ports are behind the front sight..
You should actually shoot one first, since ports do not do what a true compensator does. Drilling port holes in the barrel has virtually no effect IMHO, and I have about five ported barrels.
A true compensator has an expansion chamber where gases going forward expand out and hit a wall to offset recoil and reduce muzzle flip. Ports do very little because there is no expansion chamber.
Plaxco does a good job explaining why this is so in his book Shooting From Within.
It's also generally accepted that ports and compensators only have a usable effect on very high velocity rounds.
Thank you for your explanation but for informational purposes and to avoid any confusion we shall consider the Glock C-models to be compensated since that is how Glock refers to them and I believe the creator of this thread meant those particular models only, not what you just described there...
By the way to answer the question here there is no rule against owning a C-model, I am not LEO or military and I own a G17c and it works great, I absolutely love it
