I've been looking at the CT site and things have changed quite a bit since I bought my CT laser for my fullsize M&P.

I'd like to get one for my Shield. It looks like they all are attached to the rail now, is that right?

Which red laser CT sight do people recommend, if there is more than one for the 9mm Shield? I dont think I want green or one with a light.

No discussion of the pros and cons of laser sights (in general) is needed...I have read many discussions and feel I am sufficiently aware of both sides. Thanks.
