While I cannot be completely sure, the Crosman Stinger P9 seems to be based on the Walther P99.
Best to take it to a gunsmith.
The stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.

I'd say the Crosman Stinger P9. I'm an experienced airsoft player and have been playing for about 2 years now. I've had my trust P9 for a long time, and it always functions flawlessly. Plus, the P9 has a high capacity magazine which is nice because it makes it easier to load and it holds more bbs. The more bbs= less time loading. The P311 doesn't look like it has this feature.

It's a repeater. It's not semi-auto.
Best to take it to a authorized repair center

The slide lock and release lever on the P9 was removed from the P9T.
