I have over a dozen Civivi's and can easily say that this is one of their best designs. I expected it to feel a bit like the Praxis in hand due to the size, but the handle is both thinner and not as tall. It does feel great in hand though, and despite looking a bit heavy on paper, it has a great balance and feels very nimble. I love the inclusion of the lockbar insert which prevents overtravel and probably lets them tune the engagement without the risk of scrapping a frame. The Sinisys is insanely good for the asking price and is really a hidden gem. Pick one up before people find out about it and it gets hard to find.

Good fit and finish. Perfect detent. My only suggestion for CIVIVI would be to add a thumb stud.
