quick summary: POS.
detailed summary:
I have a lot of red dot sights; they are primarily all made by Ultradot and include the regular 1" 4MOA tube sight and the 30mm 2-to-8MOA Matchdot sight. I have 7 Ultradots and have also owned some cheaper reflex sights, like a Mueller Optics Quickshot and another brand very similar in design.
The reflex sights I have used wouldn't hold zero and would not stand up to .45ACP reduced power loads in a frame-mount configuration. The Burris was no exception.
I mounted it on a bridge-frame mount on my Pardini GT-45 which is a very accurate, high-end pistol. The Burris did have enough adjustment to get it zeroed, but after a couple magazines of reduced power .45ACP, it started to turn itself off, and finally wouldn't turn on at all.
I'm going back to my tube-style Ultradots as they are highly reliable even on my 45's. Thumbs down on the Burris Fastfire 3; big disappointment.
