Good red dot, but pricy. but you do get what you pay for. - SIG SAUER Romeo-X Pro 1x24mm Open Emitter Reflex Red Dot Sight

This is a real nice red dot, I have not put it under strain with my xten 10mm yet, but allegedly it was built to handle that so unless otherwise noted it should be able to handle it. Also, if you can turn the circle dot off and make it just red dot with this model, why would anyone order the red dot one instead of ordering this model, which can do regular dot like other one but also has option of circle dot? Just sayin’.
