Yes, the Pistolkors arms are absolutely canting.
On the subject of the Pistolkors coat-of-arms, which came first, the name or the arms?
I think they came at the same time - in 1645, when Queen Kristina of Sweden ennobled the Lieutenant Jöran Olufsson of the Karelian Cavalry. He, like so many Scandinavians ennobled by letters patent, obviously emulated the "armorially derived surname" of the ancient Scandinavian noble families like Vasa, Oxenstierna, Rosenkrantz, Gyldenstierna, Gedde, Banér, Bielke, Sparre, Stenbock, Galtung, Natt och Dag, Leijonhuvud etc. But simultaneously he needed arms to derive that surname from!
In Scandinavia (particularly Norway and Denmark) where so many people have farm names as surname, territorial surnames (or titles) are not much used by the nobility, in stark contrast to both Britain, but especially France and Germany. But unlike in Russia (and Britain), any surname can't be seen as noble, they are usually either foreign (mostly German, e.g. Wedell, Von Essen) or "ornamental surnames" derived or pseudo-derived from arms, like Pistohlkors. But in Sweden ornamental surnames have crept further down than just the nobility: A farmer from Lindtorp (= Linden Croft) would for instance combine one part of the name of his ancestral hamlet with an "ornament" like
gren (= branch) and get the name Lindgren.
