I have the part already ordered from the third dealer! All send the wrong, there probably two brothers has changed the product! While on the package is on it, for P7, diameter 28mm, there is a retainer with 24mm diameter. The holder also does not match the picture on Amazon, there still is a rubber band on it. One dealer told me on inquiry that there is only this holder. The P7 fits as though somehow pure, but you have already spend a lot of strength for it, since the holder is simply too small! So I send now the third holder also back and wait for it to what are reasonable!
