I have two LaserLyte sights.One on a .44 magnum revolver,another on a
Taurus Judge.Both are great laser sights.They are red dot,and excellent for
low light shooting.The red dot however,is vertually invisible in bright daylight.
Never tried the green dot,but they say they can be seen a little better in daylight.
My theory is that in the bright daylight if I can see my factory sight good,then
I don't need the laser at that time.They sure show up good in low light and anywhere in my house,even with the lights on.Like I say they are from LaserLyte and I paid $114 each for them.
They make a laser for every gun out there.OpticsPlanet.com sells them and sometimes
you can find them on Ebay.Good look on your adventure.
