As with all optics planet products, they came in a timely fashion. I had seen other Trijicon sights mounted on other firearms, and mine seemed a little dimmer than others. Though I didn't realize this until after I had them mounted (which I had a smith install, as I am lazy and lack the correct tools). The sight picture is amazing and I did notice a general increase in accuracy. I was unsure of how the yellow rear coupled with the green front sight would look in the dark, but sighting was a breeze. Especially considering that in high stress situation, three green dots could potentially blur together, were as one green dot is easier for the eye to distinguish, therefore aim with.
Pros: More acurate than factory sights.
Cons: Not as bright as I had hoped.
