S&W 4513TSW. There are two up for sale on one of the auction boards this AM. Small - relatively for a compact, it is a 45 afterall - light weight, accurate, easily concealed and bet your life reliable. The original variant with the 6 round magazine and cut out grip is my preference. Very scarce variant of the 4513TSW as it was only produced for two years and those that own them, keep them.
