No problems with hollow points on mine. Overall, these area outstanding, solid, accurate AKs. I am very pleased with mine and only wish I would have had the $$$ to buy a couple more.
I know some SSRs are coming in (or came in) without muzzle threads and tac'ed-on slant brakes, while other have threaded barrels with either tac'ed-on brakes or removable brakes (no tac welding). They are also neutered with the ears for the bayonet ground off the FSB.
I was fortunate enough to have been able to pick out my own gun, so I got one with threads and a removable brake. I bought the one with he plastic stock because I planned on replacing it and it was a cheaper investment up front.
This is what mine looked like before..
...then I replaced the FSB with one that had the bayonet ears...
...and then I replaced the furniture with this...
...and she looks like this now:
