I finally ran across a 5906 that I couldn't pass up. The price was right, condition is excellent, and the only downside I can see is no original box.

Put it on layaway so I'll post pics once I pick it up. Adjustable sights, rounded backstrap. It is the perfect companion to my Camp 9 that I had always been looking for. Depending on how she does with it, I'm thinking that the 5906 / Camp 9 combo with interchangable mags will be the perfect setup for said wife.

Still would like 5926 and 5904 eventually as the S&W 3rd gen sickness runs deep.
