Feature  : 

It's important to hit the things you shoot at.

This red laser sight easily attaches to your pistol or handgun with the included mount. In no time, you'll be shooting more accurately and more confidently.

Plus, you'll be hitting meaningful targets,  like bears and ducks and manly things, as opposed to the pretty little flowers that  just happened to be in the way of your  poorly aimed shot.
Get a red laser sight, and hit your target every time.
