Next to my SIG P239, my 4006 has been the most reliable of all my pistols. It is reliable and rugged. However, the trigger is what I would call gritty even after several thousand rounds through it. I'm sure a competent gunsmith could smooth it out a bit, but the feel is not all that bad it's not that important to me. Also, the trigger/disconnect system is one of the most complicated I have ever seen. Nonetheless, as I said, it is reliable.
