What ever happened to the Browning that was DA/SA/DAO?
You talking about the BDM? I've got one, and it's a good shooter, and the skinniest double-stack I've ever seen. It was and is extremely reliable, and had a pretty good trigger (as DA/SA's go) OOTB. But the controls are definitely a little strange.... the safety is also the decocker and the slide release. It's frame-mounted, but "safe" is down (backwards from a BHP or CZ), so you can't ride the safety. The tang/abbreviated beavertail is quite low, so you can't get as high a grip on it as is now popular with pistols. I got used to the controls, but it doesn't fit my grip very well anymore; otherwise, it would still be my primary HD pistol.
And it didn't have a truly DAO mode. It has a switch you can turn to put it into "revolver" mode. If you put it in that mode, the hammer de-cocks/follows after every shot, but you can still cock the hammer with your thumb. I think they hoped that would win the favor of law enforcement agencies transitioning from revolvers, but the all-metal contruction and the complex trigger control unit probably kept them from competing price-wise with the Glocks that were suddenly flooding the market. Browning dropped production several years ago. I think they could bring back the external form and have a very viable CCW-market piece, given that it holds 15 rounds and is very, very skinny.
