Look into Comp tac CT3 Holsters . Tactical Consideration Youtuber has a review of them and says they are the fastest Holster he's ever used . If you want just Level II they have those as well Walther has them right on their site . Search PDP Holster and it pulls them all up . Your light is listed . And they are open bottom . They also don't require you have your light on to use the holster . I bought one for the PDP Pro Compact . I don't have a light on this gun Nor do I plan on one . So I just ordered the holster for the 4.5 inch without a light . They have the 5 inch and 4.5 with or without lights . Just make sure it says IN STOCK . Oddly , you can't find them on Comp-Tac's site for Walthers . You have to buy them from Walther . Staccato has the same deal if you want a Blackhawk holster for a Staccato. EVen Safairland , Dara and Hammer Armament have what you are asking for .
