I recently had the chance to use my friend's Elite Force 1911 tac with a small laser sight mounted on a rail. Since my local field is super close quarters, the sight was very beneficial as I didn't really have to aim. I want a similar system for my M9, but it doesn't have any rails. Is there anyway I can mount a laser sight (or a laser/flashlight combo) to an M9? Is there one you can buy to mount on the trigger guard?
