Around 1999 or 2000, a coworker offered to trade a 3913NL straight across for my 6906. I hesitated at first because I'd owned one a couple years earlier and didn't like it, but he convinced me that it was a good deal, so I did it. I had trader's remorse for quite a while until the comparative "lightness" (not that much, but noticeable when you carry it 8 to 12 hours per day) and the quarterly superior scores at the range vs. the larger gun started adding up. (I still don't know what my problem was with my first one - maybe I didn't take enough time to adjust my grip from the fatter 6900-series?) I still have it, going on 8 years into retirement, and still take it with me for every range trip. I've since acquired a couple more 3913s, a 3914DAO, and a Zanders 908, all documented here on the forum. It turned out to be a great design for me.
