Plus the TSW guns had frames and slides that were made as matched sets. fitted with oversized frame rails.
I routinely run a search for "TSW" on Gun Broker. Most of the time it's ten or a dozen .40s, hardly any 9s or 45s are in circulation. There's actually usually more 356 TSWs than 9s or 45s but that's another story. Those guns were built extremely well and it seems like people are holding on to them. I'll come across a 5903TSW one of these days, but it may take some looking.
