Red dot on cz75, a good product - Burris FastFire III Reflex Red Dot Sight

I found a dove-tail adapter for the Burris on a CZ75 so I bought this sight. Installation was easy and zeroing also went smoothly. I took the CZ to the range today and set up 5" square targets at 10', 21', 30', 45' and 60'. I fired at what I would call a controlled rapid rate. All the rounds at 10' went through a single hole. At 21' and 30' all the rounds penetrated the 5" target and at 45' and 60' half the rounds were in the 5" square even though the red dot covered the entire square.

I expect the sight to hold zero. I use the "automatic" brightness control and was in a fairly dark indoor range. I will take the CZ outdoors next week and see how it does in bright sun.

I am a satisfied customer. I am giving the Burris 4 stars until I see battery life plus I am not loving the 5 click switch (Off-Auto-High-Medium-Low-Off). When carrying I will keep the sight switched on in the automatic mode so I want to establish an average period for battery changes.
