IIRC the P990 is just a DAO P99, so the backstraps should be the same. I would imagine that Earl's probably has them, but the price will probably be quite high. I'd just call up the new Walther customer service and see if they can get them for you. If they're anything like P99c mag floorplates, they'll only cost you a few $.

 

Yep, takes the same backstraps...see this link http://www.carl-walther.de/public/downloads/manuals/2688468_j_ET_P99_DAO.pdf it's part no. 38. I'd say wait a month or two and call Walther customer service and you should be able to order what you need.

 

Appreciate it! Definitely helpful! Honestly didn't even think about contacting Walther. Ha makes sense! Thanks!

 

Why do I need to wait two months?

 

Walther just established a new customer service operation in the USA, and things are still working themselves out.

Im the meantime Smith and Wesson still has plenty of random Walther parts. They have had most of what i needed whenever I call. Just ordered a P99 front sight screw last week. Have a part number ready or you won't have much luck. Part numbers can be found in the FAQ P99 page. There is a link to a complete blown up diagram with part numbers and names.

 

Try Numrich gun parts for the Walther p99 backstraps. For $21.20 plus shipping you get 2 backstraps and a complete sight set.
