If you own a smith and wesson sigma 9mm are there any problems with it?

The early Sigma series had a lot of reliabilty issues and accuracy issues. S&W seemed to work out alot of those bugs with the newer versions of the Sigma. I have a newer Sigma (fourth generation) in .40 cal and have not had a single problem or malfunction with it in over 1500 rounds. Accuracy is just as good as my sig and close to my HK. If it is a newer generation Sigma, you should find it to be quite nice.
