Note:
I wouldn't love being armed with only an SKS or M38, but it would be just fine in a survival situation. Both would be ok if you going to be a sneaky Pete and shot and scoot. That being said I find the SVT-40 to be a highly underrated firearm it certainly has more grace than many battle, it feels like a hunting rifle and points and shoot really well.
