I think I'd like to add a flashlight with a pressure activation switch to my Mossberg 590. Any recommendations for mounts and lights welcomed. Thanks, JR

I added a picatinny rail to the bottom of the forend and put a streamlight tlr on it

Light must be mounted so it does not cast a shadow from the weapon It must mounted solid so it cam not move. Out of they way so not in interfere with grip or loading and clear of any other sites you may want.
This one has a momentary switch remote Recommended. It also has a side mounted green laser that doe not get in the way of using iron sites.
Here is one option that works.

I'd really like brand names, models and sources of what you've used and like. Thanks, JR
