Printing all depends on your holster, what position ya carry at, your body shape, and to the least degree, the shape of the gun.
Now however unless you carry in an area where there's laws regarding printing or social predjuce/paranoia about seeing people carrying guns, printing is more a personal paranoia than anything else these days.
The whole "they can see the outline and everybody is staring at my gun" feeling goes away, as you get more comfortable with carrying to the point that it's sorta routine.
I've owned and carried both. Bought my Vp9 before the little brother hit the market. Bought the sk about 6 months after it came out.
The sk is definitely easier and more comfortable to carry, tho the size on the VP9 isn't all that bad.
I thought I loved the VP9 when I got it, but I hardly ever touched it after getting the sk.
Literally the only thing sacrificed witthe sk is the 3 finger grip. Which means shifting grip for loading/ejecting mags. Everything else is just as good as the big brother.
