The thing that caused me to sell my BD, (it was a fine gun) was the highly irritating loaded chamber indicator (LCI). Now, it probably doesn’t bother most, but I’m kind of OCD with stuff like screws backing out and parts falling off after as few as 100 rounds. And yes, I realize Locktite can mitigate the problem. But mitigate is not permanent repair. It’s a craptastic design on a beautiful pistol that caused me to sell it. That’s my two cents on the 97B/BD.
For the OP, I would go with the BD, if available. Notwithstanding the LCI (again, just my opinion), it is an excellent firearm. It’s a big girl, that’s for certain.
