I'm a fan of the .357 sig.my first was a hk usp compact then a sig 229. I put off buying a .357 bbl for the .40 s&w 239 because I knew they were readily available.the first time knew they were discontinued was when I read this post this morning.Didn't expect to get a bbl from sig but I called anyway.I was very surprised when the man said he had 1 left,so thanks for the info.
