No it hasn't.
There have been two failures.
The first one occurred was a possible drop safety failure.
This (the one you've pictured from pakguns) was the second one where flaws were found in the slide material of a small batch. As a precaution however, the initial recall of just C pistols was extended to the F pistols too.
That's two documented failures. How can you categorise two as "many".
Erm, yes it can. My uncle (in Texas) still has his F model and uses +P ammo.
Not sure what the prices are in Pakistan but they were available in the US for $450-$500. That's about mid range for a 9mm and certainly not on the cheap side.
Besides, if they were so dangerous and flawed, why has the caracal kept the same design and material for its cp660 line up?
All they've done is alter the sights, slide serrations and the grips.
The only area I can criticise caracal is in their customer support. It took multiple emails and calls for my uncle to get a refund on his c model.
