Fired about 30 rds, no problems or issues at all. Started with 1, then tried a pair, then 3, finally went through a whole mag. Can't comment on accuracy, with no rear sight, but I'm pretty sure I hit the side of the hill! I wasn't going to stomp through 3 feet of snow to verify it though. Stomping through 2 to get to the firing line was bad enough.
Recoil is almost non-existent.
Now that I know it functions properly, I will save up a little dough and get some sights. When the snow finally, melts I will be able to check it for accuracy.
