A firm case for high mag capacity ……. with every shot, you see where they have moved to!!! Like the song “ freeze frame “! & those batteries don’t wear down 😆 I actually have my first weapon mounted light in transit now. Never been a fan of them, prefer hand held. I have a couple of Streamlight Nightfighter X’s that have been bullet proof lights & some dive lights that will smoke your eyes out & a few rechargeable headlamps for work & hunting / fishing. I am putting a Streamlight TLR RM 1 on my sub 2K, on bottom rail @ muzzle, so it still folds up & tucks into the back pack. This is a light with a green laser & remote pressure switch. I have wanted to set this weapon up like this since I got it, stock hard sights, with light & laser underneath, cause you ain’t seein zhit through the stock sights at night! I went with the 1 & not the 2, because it’s 1/2 the size with the same run time. Yes it’s 1/2 the lumins @ 500, but have you ever been in a totally dark room & lite up a 1000 lumin light??? Yeah, everyone is seeing spots! I’ll stay with the 500 & see how that works. My Nightfighter is only 250, I think, & it’s perfect. Should be in soon, I’ll let ya know how it works out, couldn’t pass up the Optics Planet sale on it, so 🤞
