The Glock (Universal) rail key that comes with the Streamlight is the same height as the 1913 rail key, only it’s slightly thinner, meaning that when using the Glock key on a 1913 rail, if the light isn’t tightened down it can move forward and backward a bit within the slot. Is there any problem with using this combination, just as long as the light is pushed all the way forward in the 1913 rail slot before tightening? The reason I ask is because I want the ability to switch the light between a Glock and an 870 without having to take it apart to swap the rail key every time.
I use a TLR1 on my carbine (1913 rail) that has the Glock insert and haven’t had a problem with it. It’s a light, if it moves fore and aft a little I’m not worried about it. It hasn’t loosened up on me.
Great, thanks for the confirmation, I assumed it would be ok as long as the light is pushed all the way forward before tightening, I don’t see how it could move backwards from recoil.
