Im looking to add a some sort of laser sight to my 36. With the 36 not having a lower rail (one reason why i chose the 36) we're limited on laser sights. So the choices im considering are CT laser grips/ LM guide rod/ LM trigger guard/ LM laser sight. Im leaning towards CT laser grips or LM trigger guard. I like the LM guide rod laser the most but i have concerns with replacing the factory guide rod with what may be a lesser quality product. Anyone have any experience on the 36 with these products?
