Yes. I own this light and it will fit any pistol with a Picatinny rail using the glock key. Mine came with this key installed already and I’ve tried it on my Picatinny rail pistols as well as full size Glocks. Locks down nice and tight. Add a small drop of red Loctite on the screws once you’ve determined you’re going to keep it on a single pistol. Great light indoors and out.
