I have had all of the CZ’s. Shadow 1 and 2. They shoot great, but for me, my trigger finger touches my support hand while shooting, I never cared for it. I picked up a Q5 SF on a whim, and loved it. Added a sprinco trigger kit, it just works for me. It’s a very accurate gun, easily shooting an inch and a half @25, with syntech 124’s. I liked it so much, I sold my Shadows, and bought another Q5 SF. It is now my production and carry optics pistol of choice.
