Here's my Model 40-1, shipped in November, 2007 (fired case dated 11/01/07) and purchased new by me 1/26/08. I added the grip adapter to give more purchase on the grip safety, which is fairly stout to compress. Serial number is DBJ90XX. It would appear that the 40-1 series was therefore introduced in 2007, not 2008 as stated in the original post.
