FWIW:
I bought my NIB 3913LS last year from CDNN. ($399.99).
My 3913LS was made 2/08.
You might give them a call from time to time as their inventory changes by the minute..
At the time I bought my 3913LS I had checked the online sites (
www.gunsamerica, auctionarms,etc)and there were a couple for sale there, but generally used. As the other gentleman said you should also consider the 3913NL (no logo) and the standard 3913. THE NL is the very same pistol as the LS (even visually) while the standard 3913 is the same pistol with the straight "dustcover" (lower frame appearance) or whatever it's called. All models offer the same functionality.
Best Wishes,

P.S. I would sell you mine, as I prefer my CS9, but my wife won't let me... She loves it.
