I just got my new Thunder CC in yesterday and took it to the range today:

Had similar issues as you reported. Problems chambering the last or second to last round in the mag and the slide felt a little sticky about 3/4's of the way back.
stripped it, cleaned it, lubed it.. fine for to mags and then problems again.

stripped it again and realized the problem- Stupid me- i'd put the spring on backwards when I disassembled it the night before to clean off the factory oil.
I popped off 3 mags after that without issue but was out of ammo at that point and had to cut it short.

I'll try it again tomorrow and let you know how it works. The slide doesn't stick anymore though
