Rear Sprocket ?

Resently I tried changing the stock 44 tooth rear sprocket to a 41 (9-hole). The new 41 will not fit correctly on the chain (415 size). I have filed and ground the teeth ever so slightly to get a closer fit, but the chain still wants to jump the sprocket. I got the sprocket from GasBike, and my question(s) to ya'll is/are... Are all these sprockets made by the same outfit? Will ordering another sprocket from a different outlet get me better or the same results. Thanks in advance for sharing your knowledge!
I believe MBrebel has the largest selection and best quality. Check them out...
 
also if you are still using stock chain I highly recommend a 415HD Industrial chain. Some prefer 420 or 41 roller chain but I find the links too large.
