Have run Wolf through my P11 without issue, but the factory recommends against using steel case ammo which Wolf is. Not only the steel issue, but Wolf has a laquer coating (to minimize rusting) and running it through a hot gun can cause some gumming, sticking, etc. The steel case is hard on the ejector and the laquer can mess up the eject process. My P11 has never jammed, ever, but I haven't had it 10 years, either...........
