My CCW (from SC where CC is the only legal carry) is a Heckler & Koch USPc .40 that I carried for about ten years.
My OCW is a SA 1911-A1 ol' reliable.
My first and most beautiful pistol is a new Interarms Luger in black satin. I hope that someday it can be my dress OCW.
There have been others along the way, a KelTec P-32 (too small for my hand), a Mauser P-38 (couldn't hit a barn from the inside), a .44 Mag (too small grips)...
