Really nice product. - SIG SAUER Romeo1 1x30mm Mini Reflex Sight, 3 MOA Dot

Aquired one on a Sig 320 with it mounted. I still shoot Bullseye and this is as good, or better, as any red dot sight I've used in 28 years. Leupold, Ultradot, Aimpoint, Burris, any I've used. Adjustments track correctly. Virtually no distortion (that I can see)! Great price point with a 10% discount for military, law enforcement. As to durability, I have only a couple thousand rounds down range with it, but the guarantee is forever, and it's a Sig. Everyone that has looked thru it has been favorablely impressed, and there have been a few. I shoot Tac Optics twice a week here in Phoenix. Thinking of trying one on a slide mount Bullseye gun.
