I got this LED flashlight, works great.
I have never seen a brighter LED light. It’s so bright I would actually consider it my first line of defense. You get hit right in the eyes in a dark room (something I accidentally did to myself in the attic one day), you won’t be seeing anything for the next 30 seconds. The main beam BRIGHT with a secondary cone beam that helps light up the room as well.
Can’t beat the price, they come in a package of two for $30 (Sams Club). I plan on keeping one on the night stand and one on the Protector. It takes 3 AAA batteries (included), so no weird battery packs or charging to worry about.
The flashlight is 1” diameter which is what most shotty flashlight mounts are made for. I’ve already spaced it out and it fits right on the end of the mag tube. Its on/off switch is on the back cap which is perfect for this placement. With my left hand on the forend, my thumb is right there by the switch.
If you Google it you may find that there were some problems with the battery assembly breaking fairly easily but these issues were resolved about a year ago. I haven’t had any problem with mine so I think I might have gotten one of the first batch of new ones. Even if it breaks, reports are that the customer service is great. Just tell them something broke and they send you a new one, no questions asked (note: I haven’t had to do this, it’s just what I heard). And at $15/per… I’m not all that worried about having to buy a replacement.
The mount I got was just a simple ATI mount. It’s used to either reinforce a mag extension to the barrel or (and it says this right on the package) to attached a 1” diameter flashlight to the mag tube. Only problem is, at least on the Protector, the bolt that comes with it isn’t long enough to use for the flashlight setup. I just haven’t had a chance to go to Home Depot to get a replacement that’s about a 1/8 inch longer.
While I admit I haven't yet actually shot the gun with the flashlight on and attached, I have dropped it multiple times on hardwood floors from a considerable distance (8+ feet) and it didn't so much as flicker. I think it'll be fine.
Even if you don’t put one on your gun, I highly recommend these flashlights.
