Check with Vedder Holsters. You will have to email them about it. They list holsters for glocks with Olight PL Minis and Pros, but the Walther list doesn't mention any lights. They are good people to talk to though and damn fast with their holsters. I have two of their products. An outside the waist pancake style for my Q5 and an IWB style for my XDs 4". Both very good holsters.
