I own a VP9sk.
From all I have been able to learn, from multiple sources, is that any sight that will fit a VP9 will also fit the VP9sk.
I have not done it yet in person, but I will do so soon . . .
No. It will not fit.
These ones, like the others, will not fit on a optic ready slide. The optics ready slides utilize the P2000 dovetail cut, but they are not the same height of the sights found on the VP9 OR for example. Because of this, if you use the P2000 sights we sell, you may see some POA/POI issues. At the moment, we do not produce sights for the OR model HK pistols.
Yes. They should fit.
Yes they should work just fine.
Yes. They are compatible.
No. It will not fit.
Unfortunately Meprolight does not make a version of this in orange at this time.
Negative. Used for both front & rear...Tim
