Hi
I recently stripped the trigger of my Supersport. I didn't intend to, but in the process of lubing the spring etc I ended up with the piston in the rear position and needed to strip the trigger to release it (although reading the comments above I see that there's a screwdriver trick I could have used).
Anyway, yes the Supersport trigger is more complex than a Meteor trigger (and it operates all the better for it).
There is a key stage in the reassembly where the clothes-peg style spring #41 on the exploded diagram below needs to be compressed so that its short end can be tucked under a pin. The pin also holds, through a pair of eyes, the v-shaped spring that's next in the re-assembly (part #43). Getting this pin into place was a real swine and I gave up a couple of times, Eventually I succeeded, holding the gun upside down in a workmate squeezed as tightly as I dared, compressing the short end of the clothes-peg spring with a small screwdriver and eventually getting the pin into place.
After that, the L-shaped piece (#42) needs to be put in place. Although it looks like it will fit into place without removing the pin above it (this is the fattest pin, possibly part #40 and shown in situ in my second image) I found that not to be the case, and once that was removed it all went back together successfully. The finished job looks quite sloppy - there are parts that seem to have little lateral stability - but go with it and it'll be fine when it's all back under tension.
I have not described this very well - but hopefully the photos will help. Unlike the Meteor, for instance, I found very little on the web in terms of maintenance guides for the Supersport.
The good news for me is that following the strip and the mainspring clean and re-grease, the rifle has lost the twang it had acquired and is now super smooth using just the standard (polished) spring and guides.
