I’ve received lots of questions about the keys of the TLR lights. The two TLR-1 lights have Glock keys. I have used them on Glocks, Beretta px4 storm, HK P series, and CZ P series. I may have more to fit whatever you have so ask. I have like 10-15 TLR-1 lights around here so I’m sure I have the parts to fit your gun somewhere around here.
The TLR-VIR whatever has a 1913 key if anyone is interested.
