The sheepsfoot is proud on most stockman knives. That can be both a good and not-so-good thing, depending on how you use the knife, including how you grip it. I haven't had any major issues with the grip, because I tend to hold the knife with fingertips alongside (on the scale covers), instead of a full-fisted grip, which would put the sheepsfoot's spine into the crease of my fingers. As mentioned, a proud blade is easier to open with a gloved hand, so I can respect that. I personally haven't felt the need for keeping it that high, in my own use.
It's usually pretty easy to lower the sheepsfoot, at least a bit, if one feels it's too high. Filing down the kick under the tang can make a positive difference, if done carefully to keep the blade from going too low (blade edge colliding with backspring, or nail-nick getting obscured behind an adjacent blade). I ground the kick down on my Queen #49 Cattle King to lower the sheepsfoot, which was easily 1/8" higher than the spine of the clip blade, when new. The ground-down kick can be seen in the first pic below, on the left (compare to the taller kick on the spey at right). It's now virtually dead-flush at the spine, and even 'invisible' when viewed from the mark side of the knife:
