Pass this up. I know it's hard for the price, but I put this on a Taurus 24/7 Pro .40 cal and within 5 shots the laser was 3 feet off and traveling with each additional shot. Then the internal pieces broke so I could not adjust it. NcStar's CSR is great, but it's not worth the money. Get something better.
