Does anybody know if Streamlight TLR's need to be re-zeroed if you move them from one Glock to another?

yeah, every gun shoots differently

If it's just the flashlight - why would you need to zero?

I would have to assume he's talking about the laser equipped models.

 

And yes, you should zero for every weapon.

Not only for every different weapon, but every time you take it off and put it on the same weapon, the zero should be verified. This is especially important if the laser is intended for "social" purposes.

 

The attachment method of the TLR series WML are not conducive to a return to zero mount. And neither is the rail platform on the Glock series pistols. (any polymer pistol really)

 

A quick confirmation of the laser dot over the irons at the distance you want it to hit POA/POI is OK for a quick and dirty zero check, but should really be shot at the distance you want the laser zeroed at.

 

Good luck!

I was just gonna say- if it's a flash light what would you be zeroing?

 

And even if it's a laser, "zeroing" it is about the easiest thing in the world, you can literally see the point of aim vs. point of impact vs where the laser is on the paper vs where you are aiming etc. , simple as pie.

 

And again, if it's just a light model, I would not think twice, swap away as long as they fit.
