I have both; the Caracal has a better trigger and less felt recoil. To me, handling characteristic's are different; the Caracal points up and the Glock is more of a down angle in my hand due to the bore axis.
At 7 or 10 yards, I shoot a better group with the Caracal. I only have around 500 rounds through it but it's been flawless. If it's as reliable as the Glock over time, then it's a winner at $400.
