Better than expected - ADE Advanced Optics RD3-009 1x Reflex Red Dot Sight w/Taurus PT111 G2, Millennium G2 Optic Mount Plate

I normally buy more expensive optics, but I wanted something affordable for my backup pistol. This surprised me.

The machining on the mounting plate is clean, the finish matches the pistol nicely, and everything fit tightly without any wobble. Zero held through several hundred rounds and the controls are easy to use with gloves.
