The 3906/4 has great balance and artistic lines.

I haven't been able to find one to purchase.

I do have it's cousin, a S&W 909, which is the "value line" slim-jim carry version. Black, light weight frame, single sided safety. For kicks, I also have a complete upper from a 908 which interchanges perfectly on the 909 for a hybrid with a 3.5 slide/barrel.

Some folks dream of winning the lottery; my dream is to find a person with a giant safe full of extra 3rd Gen S&Ws. Not going to happen is it?
