I did get a chance to call Browning re this question. The response was: "The 13-round magazines should fit and work properly."
LightningLink,
There is a Beretta 84F 13RD 380 Nickel original mag up for auction at AuctionArms. The auction ends 3/22/01, just in case you are interested. Currently the price is $45.00. Thanks for your reply.
VonFatman,
I already purchased a BDA 380 at a gun show a few weeks ago. It came w/ 2 13-round magazines. The BDA is obviously used. I was just curious if I purchased a newer BDA would the hi-cap mags fit. I own a CZ75 and would not hesitate to purchase another CZ product. Thanks for your reply and suggestion re CZ83.
