I spent a little bit of time behind a PSA Dagger with a Holoson, not sure of the model. It was a 6moa donut. I got to say, I was very impressed with the Dagger, especially for the price. Much more comfortable to shoot than the Glock gen4 and 5s. The trigger was good for a stock gun, and it was shockingly accurate, putting 2 out 3 shots on a 3" plate at 50 yards. The donut dot on the holosun made it surprisingly easy to hold on small targets and not need to aim with the top of the dot. While still being bright and easy to track at speed. But I don't think I would trade a solid 6moa for the donut.
