Vertical shoulder holster is a breeze with this one. It's one of the most forgiving methods of carry in general and the P99 is relatively compact for a full-sized pistol. Of course, this comes with all the added considerations of shoulder carry. Mainly, it's only viable when you can count on wearing an appropriate cover garment the whole time you're out in public. It can be a blazer, a leather jacket, or even a thick enough cardigan sweater. You just have to be wearing it.
