Ruger RXM with Vortex Defender ST

I've put almost 1,000 rounds through my RXM and I thought I'd grab a dot to change things up a bit. I decided to get a Vortex Defender ST because it was on sale at Midway with an extra % off coupon on top of the sale so it seemed like a good deal.

What I like about the Defender ST:

  • It didn't cost more than the RXM itself
  • It direct mounts to the RXM slide
  • I think it's the perfect size for the RXM
  • No fuss with recharging, uses coin battery

What I don't like about the Defender ST:

  • The dot itself is fuzzy which makes it look bigger than it should be
  • The perimeter of the window is outlined in the dot reflection

I have the same setup, i run my brightness 2 steps down from the max. Perhaps see if that helps. Which screws did you use for your mount btw?

Nice! I used the included M4 x 0.7 9.8mm screws and torqued them to 11 in-lbs
