What is everybodys opinion on the S410 - SL XTRA FAC .22. Is this a worthwhile upgrade from an S300? What does the SL stand for? There doesn't seem to be many people opt for this rifle, can anyone tell me why.
Thanks
Heres a pic of my S300.(taken from air arms owners club - dont know how to add one here)
