Barska laser - Barska GLX 5mW Green Laser Sight w/ Built-in Picatinny Rail

This is an ecxellant laser for the money. It performs very well.It was dead on when mounted right out of the box. The onle problem I had was that there were no deminisions given in the description. I purchased this unit for a mid frame size semi-automatic handgun and due mount lenght requirements the unit is too long for a secure mount on this size gun. It should be used only on full frame guns, rifles, or shotguns.
It works good enough I am not returning it but mounting it on another gun and ordering a micro for my handgun.
Pros: This is an excellant value for the money.
Cons: there are no mention of overall deminisions in the product description
