The .356 TSW was discussed just a few days ago. Somebody posted a copy of an ad where that cartridge was proudly compared to what is obviously some defective and underpowered 140 gr. .357 Magnum ammo. I don't remember if it was Lew Horton's ad though.
I couldn't find the PC940 .356TSW add with a search engine but did find a post at the High Road when the seller you bought it from had just bought it for $500..
Here's that link if it'll post here S&w 940 .356 tsw - THR
Note the green grips, That is you..
