I bought the Caracal F when they first came out. Liked it, and bought the C model. Then there was the recall on the F so I sent in and requested the Quick Sight model, and that's what they sent me, and I really liked the sights.
When they issued a recall on the C model due to "catastrophic failures", I sent it in for a refund which I received, hoping they would rectify the problems, because I really liked the gun. Never happened, obviously.
I still have the F QS gun. It has given me no problems, and I use it as one of my boat guns in FL.
