Yes on the Burris. I have 4 or 5 of them and have been using them since they first came out. I am very happy with them. One has been on a P-09 in a dovetail mount (Springer Precision) for maybe 10,000 rounds, no problems. Another has been on a CZ-97B"E" for maybe 5,000 rounds, no problems. Another on a 75B 9mm, no problems, and one on a CGW slide cut P-10C, no problems, but the last two don't have many rounds through them.
The one I am having a problem with is the newest one and it intermittently just shuts off. I need to check the battery compartment contacts, might just need to bend them a little.
I have a problem with the dot intensity settings at times, depending on the shooting range conditions. Many times in the winter, when it is gloomy at the range early in the morning, the dimmest dot is too dim and the next one up isn't crisp enough for precision shooting at, say, 100 yards. So my only concern from a feature standpoint is I sometimes need more options for brightness. That is really my only reason for trying the Holosun, as I am assuming this one Burris sight may have to be sent to Burris for repair, and I am not even sure about that yet. And I need another red dot anyway so that I can leave one on the 75B.
So, no complaints about the Burris at all. More of an old guy shooting at sunrise in the mountains problem than a Burris problem.
