The Walther PDP FS 9×19 10-round magazine suits the PDP Full Size pistol only.

The PDP Full Size has a longer grip than the regular 9mm frame.

****This magazine is NOT suitable for use in any other Walther 9mm handgun:

PPQ M2/ Q5 Match/ Q5 Champion/ Q5 SF/ Q5 SF Champion/ Q5 SF Expert/ Q5 SF Black Ribbon/ Q5 SF Black Tie/ Q5 SF Black Diamond/ Q5 SF Patriot/ Q5 SF Vintage/ PDP C

If this magazine is used in the above models, the ejector will be damaged due to the increased length of the magazine resulting in overtravel.
