Glocks and lights

I have a gen4 Glock g17. I also have a stream light tlr1 hr. It mounts fine on a picatinny rail.  The lug on the light is marked 1913.  It won't snap into the slot on the Glock.  Is the Glock mount different?

According to Streamlight's web site, the TLR 1 "Includes keys for GLOCK®-style rails, MIL-STD-1913 (Picatinny) rails, Beretta® 90two, Smith & Wesson® SW99, and Smith & Wesson® TSW".

Thank you. I'll have to look in the box.

I found the box and it turns out I have 2 1913 keys and no Glock key. I'll give stream light a call Monday and get the appropriate lug.

I haven't mounted a light on my Glock 19X yet but the TLR-9 I mounted to my Girsan (92FS) rail took a bunch of messing around with different keys until I found the perfect one!

A call to stream light was all it took. The proper key is on the way.

No, no. The rules state that you’re supposed to buy a gun that fits the light you have and buy a new light for the Glock.
