I have a 97BD coming Monday. I wanted the B, but moved a little too slow, so I spent the extra cheddar on the BD. Been trying to get one of these for about a year, so I didn't mind the extra money spent.
As to the question: My P 07 Duty came with the parts to convert from decocker to thumb safety, which I did. I'm not a decocker guy. Can the 97BD be converted? I'm assuming you could, but we're all aware of what happens when you assume, lol. Seems the frame and internals should be the same, but I may be wrong. In the end, it's not a big deal, since this will be range only, never carried.
