Not worthy of the sig name - SIG SAUER Romeo1 1x30mm Mini Reflex Sight, 6 MOA Dot

The Romeo one fits the precut Sig slides. I can not think of an other reason to buy the Romeo over some other similarly priced sights. The paint easily scratches. The battery cap can easily be over tightened. I have seen videos of the sight failing a drop test. But..... the sight fits the sig Xseires perfectly. The red dot is easily acquired and adjusted. Many of the negative attributes can be overcome with the purchase and installation of a shield made for the Romeo one. The shield is $50. I highly recommended the purchase of the shield if you buy this sight.
