The new RDD is outstanding, have it on my
P226.

The thing that stands out to me as being most outstanding is this company’s customer service.

Chuck.

Looks like it’s everything it is advertised to be. Holosun makes such quality products. Have three now, with two 507k’s, one in green and one in red, mounted on a G43 and a S&W .22 mag. Love the 32 MOA circle reticle, but looking forward to the 8 MOA circle on the COMP.

Very happy with this optic. I also use a different Holosun enclosed optic on a separate pistol. Really like the different Comp reticles. I primarily use the 2 moa dot with the 8 moa ring. But I like having the other options. Very happy, would definitely purchase and use this optic for any pistol.

Excellent have several Holosuns, 507 comp is
my favorite. Large window easy sight acquisition

I love the large window and the selection of reticles. The only problem I have had is with the recessed + and - buttons as they are hard to function. You must must in a specific portion of the button or there is no changing. Also the RDO at this price should include a dust cover.
